unc-33 encodes a conserved member of the CRMP/TOAD/Ulip/DRP family of proteins that includes mammalian CRMP-2 (Collapsin response mediator protein-2), which is essential for axon guidance and axonogenesis; in C. elegans, unc-33 activity is required for several biological processes including outgrowth and guidance of sensory, motor, and interneurons, sex myoblast migration, normal body movement and morphology, egg laying, and defecation; by homology to CRMP-2, UNC-33 is predicted to bind tubulin heterodimers and promote microtubule assembly, thereby regulating the extension and branching of cellular projections during neuronal polarization; UNC-33 is reportedly expressed exclusively in axonal processes from after early embryogenesis through larval and adult stages.
Enables filamin binding activity; protein heterodimerization activity; and protein homodimerization activity. Involved in several processes, including axon guidance; establishment or maintenance of cytoskeleton polarity; and regulation of locomotion. Located in neuron projection. Expressed in amphid socket cell; neuroblasts; neurons; pharyngeal cell; and somatic nervous system. Is an ortholog of human DPYSL2 (dihydropyrimidinase like 2).
sequence match was given and M57.b and.c but theses overlap with Y37E11C.c which has not been annotated yet. sdm 11/00. will probably acquire name Y37E11C.1
