unc-119 encodes a novel protein that is highly conserved amongst metazoans; unc-119 activity is required for proper development of the nervous system, including axonal branching and fasciculation, and hence, for normal movement, chemosensation, and feeding; unc-119 is expressed pan-neuronally beginning in the early embryo (~60 cells) and continuing through adulthood; although the molecular function of UNC-119 is not yet known, human UNC119, which can rescue C. elegans unc-119 mutant animals, is reported to function as a receptor-associated activator of signal transduction; thus, UNC-119 may be part of a signal transduction pathway that mediates axonal patterning in response to external developmental cues.
Predicted to enable lipid binding activity. Involved in several processes, including body morphogenesis; dauer larval development; and regulation of multicellular organismal process. Located in axon. Expressed in several structures, including body wall musculature; ganglia; neurons; seam cell; and somatic nervous system. Human ortholog(s) of this gene implicated in cone-rod dystrophy and immunodeficiency 13. Is an ortholog of human UNC119 (unc-119 lipid binding chaperone) and UNC119B (unc-119 lipid binding chaperone B).
