The only exception should be when experimental data (e.g., staining with trypan blue or propidium iodide) show that cell death has occurred, but fail to provide details on death modality (accidental versus programmed). When information is provided on the cell death mechanism, annotations should be made to the appropriate descendant of ‘cell death’ (such as, but not limited to, GO:0097300 ‘programmed necrotic cell death’ or GO:0006915 ‘apoptotic process’). Also, if experimental data suggest that a gene product influences cell death indirectly, rather than being involved in the death process directly, consider annotating to a ‘regulation’ term.

ciliary basal body-plasma membrane docking [GO_0097711]
The docking of a cytosolic centriole/basal body to the plasma membrane via the ciliary transition fibers. In some species this may happen via an intermediate step, by first docking to the ciliary vesicle via the ciliary transition fibers. The basal body-ciliary vesicle then relocates to the plasma membrane, followed by the ciliary vesicle fusing with the plasma membrane, effectively attaching the basal body to the plasma membrane. Basal bodies in jawed vertebrates appear to first attach to a ciliary vesicle. It is unclear how specific this is to jawed vertebrates or if other organisms also employ this sequence. Some species like Giardia intestinalis do not relocate their basal bodies to the plasma membrane, but have their axonemes extend through the cytosol to then protrude out of the cell to form flagella.

Also, researchers consider the composition of both the plasm and the membrane of the cilium to be detectably different from that in the non-ciliary cytosol and plasma membrane (e.g. in terms of calcium ion concentration, membrane lipid composition, and more). For this reason, the term “ciliary plasm” is not linked to “cytoplasm”.

A region of the cilium between the basal body and proximal segment that is characterized by Y-shaped assemblages that connect axonemal microtubules to the ciliary membrane. The ciliary transition zone appears to function as a gate that controls ciliary membrane composition and separates the cytosol from the ciliary plasm. Depending on the species, this region may have a distinct geometrically shaped electron-dense structure within the axonemal lumen visible in electron microscopy images; most animals don’t display this inner structure. The axoneme extends through the ciliary transition zone, but only consists of the outer doublets. The central pair, axonemal spokes, and dynein complexes are not found in this part of the ciliary shaft. Note that the connecting cilium of the photoreceptor cells is thought to be equivalent to the transition zone.

A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface and of some cytoplasmic parts. Each cilium is largely bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored to a basal body. Note that we deem cilium and microtubule-based flagellum to be equivalent. In most eukaryotic species, intracellular sub-components of the cilium, such as the ciliary base and rootlet, are located near the plasma membrane. In Diplomonads such as Giardia, instead, the same ciliary parts are located further intracellularly. Also, ‘cilium’ may be used when axonemal structure and/or motility are unknown, or when axonemal structure is unusual. For all other cases, please refer to children of ‘cilium’. Finally, note that any role of ciliary proteins in sensory events should be captured by annotating to relevant biological process terms.

mitotic cell cycle [GO_0000278]
Progression through the phases of the mitotic cell cycle, the most common eukaryotic cell cycle, which canonically comprises four successive phases called G1, S, G2, and M and includes replication of the genome and the subsequent segregation of chromosomes into daughter cells. In some variant cell cycles nuclear replication or nuclear division may not be followed by cell division, or G1 and G2 phases may be absent. Note that this term should not be confused with ‘GO:0140014 ; mitotic nuclear division’. ‘GO:0000278 ; mitotic cell cycle represents the entire mitotic cell cycle, while ‘GO:0140014 ; mitotic nuclear division’ specifically represents the actual nuclear division step of the mitotic cell cycle.
mitotic cell cycle phase [GO_0098763]
One of the distinct periods or stages into which the mitotic cell cycle is divided. Each phase is characterized by the occurrence of specific biochemical and morphological events. This term should not be used for direct annotation. If you are trying to make an annotation to x phase, it is likely that the correct annotation should be to ‘regulation of x/y phase transition’ or to a process which occurs during the reported phase (e.g. mitotic DNA replication for mitotic S-phase). To capture the phase when a specific location or process is observed, the phase term can be used in an annotation extension (PMID:24885854) applied to a cellular component term (with the relation exists_during) or a biological process term (with the relation happens_during).

mitotic interphase [GO_0051329]
The cell cycle phase following cytokinesis which begins with G1 phase, proceeds through S phase and G2 phase and ends when mitotic prophase begins. During interphase the cell readies itself for mitosis and the replication of its DNA occurs. Note that this term should not be used for direct annotation. If you are trying to make an annotation to x phase, it is likely that the correct annotation is ‘regulation of x/y phase transition’ or to a process which occurs during the reported phase (i.e mitotic DNA replication for mitotic S-phase). To capture the phase when a specific location or process is observed, the phase term can be used in an annotation extension (PMID:24885854) applied to a cellular component term (with the relation exists_during) or a biological process term (with the relation happens_during).
mitotic M phase [GO_0000087]
A cell cycle phase during which nuclear division occurs, and which is comprises the phases: prophase, metaphase, anaphase and telophase and occurs as part of a mitotic cell cycle. Note that this term should not be used for direct annotation. If you are trying to make an annotation to x phase, it is likely that the correct annotation is ‘regulation of x/y phase transition’ or to a process which occurs during the reported phase (i.e mitotic DNA replication for mitotic S-phase). To capture the phase when a specific location or process is observed, the phase term can be used in an annotation extension (PMID:24885854) applied to a cellular component term (with the relation exists_during) or a biological process term (with the relation happens_during).

mitotic sister chromatid segregation [GO_0000070]
The cell cycle process in which replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the mitotic cell cycle. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner. One homolog of each morphologic type goes into each of the resulting chromosome sets.
modulation of chemical synaptic transmission [GO_0050804]
Any process that modulates the frequency or amplitude of synaptic transmission, the process of communication from a neuron to a target (neuron, muscle, or secretory cell) across a synapse. Amplitude, in this case, refers to the change in postsynaptic membrane potential due to a single instance of synaptic transmission.
molecular function regulator [GO_0098772]
A molecular function regulator regulates the activity of its target via non-covalent binding that does not result in covalent modification to the target. Examples of molecular function regulators include regulatory subunits of multimeric enzymes and channels. Mechanisms of regulation include allosteric changes in the target and competitive inhibition.
molecular transducer activity [GO_0060089]
A compound molecular function in which an effector function is controlled by one or more regulatory components.
molecular_function [GO_0003674]
A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. These actions are described from two distinct but related perspectives: (1) biochemical activity, and (2) role as a component in a larger system/process. Note that, in addition to forming the root of the molecular function ontology, this term is recommended for use for the annotation of gene products whose molecular function is unknown. When this term is used for annotation, it indicates that no information was available about the molecular function of the gene product annotated as of the date the annotation was made; the evidence code ‘no data’ (ND), is used to indicate this. Despite its name, this is not a type of ‘function’ in the sense typically defined by upper ontologies such as Basic Formal Ontology (BFO). It is instead a BFO:process carried out by a single gene product or complex.
monoamine transport [GO_0015844]
