Predicted to enable SNAP receptor activity and syntaxin binding activity. Involved in intracellular protein transmembrane transport; ovulation; and secretion. Located in apical plasma membrane and recycling endosome. Is expressed in several structures, including coelomocyte; excretory canal; gland cell; hermaphrodite somatic gonadal cell; and vulva. Used to study chromosome 22q11.2 deletion syndrome, distal. Human ortholog(s) of this gene implicated in CEDNIK syndrome. Orthologous to human SNAP29 (synaptosome associated protein 29).
WB Description
snap-29 encodes one of the SNAP25-family of double SNARE-domain target-SNAREs orthologous to human synaptosomal-Associated protein (OMIM:604202); snap-29 is an essential gene important for development and cellular functions throughout the life cycle; SNAP-29 is required for secretion of many transmembrane cargo proteins of oocyte cells; loss of SNAP-29 leads to defects in ovulation and RNAi leads to defects in maturation of distal oocytes; SNAP-29 is involved in membrane transport; SNAP-29 regulates LIN-3/EGF secretion in the oocyte which is essential for ovulation; SNAP-29 is expressed in excretory canal, gland cells, hypodermis, vulva, coelomocyte, intestine, gonad sheath cells and some neurons.
