unc-41 encodes an ortholog of Drosophila STONED B (STNB) required for normal locomotion; a beta-strand in the mu-adaptin-like domain of UNC-41 binds the C2A domain of SNT-1, and this binding is required for SNT-1 endocytosis, punctate localization of UNC-41 in neurons, and transgenic rescue of unc-41(e268) animals; UNC-41 is also required for normal secretion of EGL-17 from P6.p cells, and for embryonic viability; UNC-41 is expressed in the larval and adult nervous system; UNC-41, like other stonins, is an adaptin, and by orthology with stonins is predicted to be a protein adaptor that helps sort SNT-1 endocytotically.
Predicted to enable clathrin adaptor activity. Involved in positive regulation of locomotion. Located in synapse. Expressed in DD neuron; VD neuron; and cholinergic neurons. Is an ortholog of human STON2 (stonin 2).
