larval DA1 motor neuron
ID: FBbt_00001447
Motor neuron that is born from the first GMC to bud from neuroblast NB1-1 (GMC1-1a) in thoracic and abdominal segments and is part of the Notch OFF hemilineage (Skeath and Doe, 1998. It has a large round cell body that sits at the dorsal surface of the CNS, in the next anterior segment to the muscle it innervates, just posterior to the posterior commissure and longitudinal connective (Schmid et al., 1999; Zarin and Labrador, 2019. It innervates dorsal acute muscle 1 (DA1; muscle 1) (Landgraf et al., 1997. It expresses even-skipped (Manning et al., 2012. (Landgraf et al., 1997, Goodman and Doe, 1993, Manning et al., 2012, Skeath and Doe, 1998, Schmid et al., 1999, Zarin and Labrador, 2019)
Not present in MN neuromere (lack of NB1-1) or LB neuromere (apoptosis of precursor) or MX neuromere (precursor cell appears to differentiate into a different type) (Rickert et al., 2018 - FBrf0238045). Present in A8 and A9 (Birkholz et al., 2013 - FBrf0221210).
