DESCRIPTION

Amphid neurons, single ciliated endings, project into ring via commissure from ventral ganglion, make diverse synaptic connections in ring neuropil. Also take up FITC.

Functions: Involved in chemotaxis to lysine, contribute to a residual chemotactic response to cAMP, biotin, Cl-, and Na+ after ASE is killed (Bargmann C.I. and Horvitz H.R. 1991). Controls entry into dauer stage (Bargmann C.I. and Horvitz H.R. 1991).

Receptor expression: Express G protein-coupled serpentine receptors, SRD-1, STR-2, STR-3 (Peckol E.L. et al. 2001). Express transmembrane guanylyl cyclase DAF-11 (Birnby D.A. et al 2000).
