DESCRIPTION

Motor neuron. Y cell becomes terminally differentiated as PDA after early larval stages in hermaphrodite. In male, Y divides and the anterior daughter becomes PDA. The dorsal cord process of PDA ends in the posterior part of the body (O. Hobert, pers. comm.). Hermaphrodites and males exhibit some differences in PDA connectivity.

Functions: Innervates posterior dorsal body wall muscles.

Receptor expression: Expresses an excitatory GABA receptor subunit, EXP-1 (Beg A.& Jorgensen E. 2002, also pers. comm.). Expresses UNC-8, a DEG/ENaC family member homologous to subunits of a candidate mechanically gated ion channel (Tavernarakis N. et al, 1997).
