Binding to a 14-3-3 protein. A 14-3-3 protein is any of a large family of approximately 30kDa acidic proteins which exist primarily as homo- and heterodimers within all eukaryotic cells, and have been implicated in the modulation of distinct biological processes by binding to specific phosphorylated sites on diverse target proteins, thereby forcing conformational changes or influencing interactions between their targets and other molecules. Each 14-3-3 protein sequence can be roughly divided into three sections: a divergent amino terminus, the conserved core region and a divergent carboxy-terminus. The conserved middle core region of the 14-3-3s encodes an amphipathic groove that forms the main functional domain, a cradle for interacting with client proteins.

Note that the polyprenyl sidechain substrate for this reaction has a different number of prenyl units in different organisms (for example, ubiquinone-6 in Saccharomyces, ubiquinone- 9 in rat and ubiquinone-10 in human), and thus the natural substrate for the enzymes from different organisms has a different number of prenyl units.

A 5’ UTR variant where a premature start codon is introduced, moved or lost. Requested by Andy Menzies at the Sanger. This isn’t necessarily a protein coding change. A premature start codon can effect the production of a mature protein product by providing a competing translation start point. Some genes balance their expression this way, eg THPO requires the presence of a premature start to limit expression, its loss leads to Familial thrombocythemia.

Motor neuron that innervates the internal dorsal acute muscle 1 of larval abdominal segments A1 to A7. Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DA1 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). By embryonic stage 16, it has a short contralaterally projecting neurite extending into the posterior commissure. It receives input from the contra- and ipsilateral larval A27h neuron. There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al., 1999), we infer A1 motor neuron innervation patterns from those of A2-7. These neurons were identified in a EM reconstruction of a volume that includes the posterior half of abdominal segment 2 and abdominal segment 3, of a 12-24h old first instar larva. The number of connections was estimated from the publication figures. The number of input synapses was the following (number in brackets ipsilateral/contralateral): from A27h (10/10) (Schneider-Mizell et al., 2016).
Motor neuron that innervates the internal dorsal acute muscle 2 of larval abdominal segments A1 to A7 (Landgraf et al., 1997). Its dendritic arborization occupies the lateral and intermediate domains of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DA2 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). The muscle it innervates is one segment posterior to its soma (Zarin and Labrador, 2019). There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al., 1999), we infer A1 motor neuron innervation patterns from those of A2-7. This motor neuron is an exception to the class of motorneurons that innervate the internal dorsal muscles whose dendrites occupy the lateral neuropil; it has dendrites in the intermediate and lateral regions (Mauss et al., 2009). Based on cell body position, the DA2 motor neuron appears to correspond to the U2 neuron (personal communication by Matthias Landgraf - FBrf0221138), however, Zarin et al.

It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DA3 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). Its soma is in the segment anterior to the muscle it innervates (Kohsaka et al., 2012). There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al., 1999), we infer A1 motor neuron innervation patterns from those of A2-7. The DA3 motor neuron is likely to correspond to the U4 neuron. This is suggested by the cell body position and by extrapolating the observation that these neurons that extend their axons the furthest differentiate the earliest (personal communication by Matthias Landgraf - FBrf0221138).

There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al., 1999), we infer A1 motor neuron innervation patterns from those of A2-7. Based on cell body position, the DO1 motor neuron corresponds to the U1 neuron (personal communication by Matthias Landgraf - FBrf0221138).

Based on cell body position, the DO2 motor neuron appears to correspond to the U3 neuron (personal communication by Matthias Landgraf - FBrf0221138), however, Zarin et al. (2019) report that the DO2 motor neuron corresponds to U2.

It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DO3 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016). Its soma is in the segment anterior to the muscle it innervates (Kohsaka et al., 2012). There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al., 1999), we infer A1 motor neuron innervation patterns from those of A2-7.

It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DO4 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016). Its soma is located in the segment anterior to the muscle innervated (Kohsaka et al., 2012). There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al., 1999), we infer A1 motor neuron innervation patterns from those of A2-7.

These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016). Its soma is found in the segment anterior to the muscle it innervates (Kohsaka et al., 2012). Muscle DO5 is only present in A1-7. There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al ., 1999), we infer A1 motor neuron innervation patterns from those of A2-7.
Motor neuron that innervates the internal dorsal acute, dorsal oblique and LL1 muscles of larval abdominal segments A1 to A7 (Landgraf et al., 2003). It exits the ventral nerve cord via the posterior root of the intersegmental nerve. It is one of the common exciters of the A1-7 muscles, innervating the dorsal and LL1 muscles via type Is boutons (Mauss et al., 2009). It receives input from the ipsilateral larval A02b, A27j, eIN-4 (A03a1) and A27e and contralateral larval A08e1-3 local neurons and A31k neuron. Unlike other ISN neurons, its soma is located in the same segment as the muscles it innervates (Zarin and Labrador, 2019). There is little or no published literature specifically on innervation in A1 and so where equivalent muscles are present between A1 and A2-7 (Landgraf et al., 1997; Schmid et al., 1999), we infer A1 motor neuron innervation patterns from those of A2-7. These neurons were identified in one EM reconstruction of abdominal segment 3 of a 12-24h old first instar larva (Heckscher et al., 2015; Schneider-Mizell et al., 2016). For Heckscher et al. (2015) only bilateral connections are reported. The number of identified input synapses was the following (number in brackets left/right): from A08e1 (1-4/1-7), A08e2 (1-4/1-7), A08e3 (1-4/1-7) (Heckscher et al., 2015). For Schneider-Mizell et al. (2016), the number of connections was estimated from the publication figures. The number of input synapses was the following (number in brackets left/right where available): from A02b (12/12), A27j (12/25), A03a1 (20/23), A27e (21), A31k (35/35) (Schneider-Mizell et al., 2016).
