CC -!- FUNCTION: Plays a critical role in several secretory processes,
CC including cuticle secretion and neurotransmitter release, and probably
CC assists in neuronal membrane maturation or the final stages of neuronal
CC differentiation. Essential for embryonic viability and development. Has
CC a role in dauer formation and adult life span. Required for locomotion.
CC Probably by regulating neuronal transmission downstream of lin-3 and
CC receptor lin-23 and phospholipase plc-3 and upstream of innexin unc-7
CC and egl-4/PKG in ALA neurons, involved in the decrease in pharyngeal
CC pumping during the quiescent state that precedes each larval molt.
CC {ECO:0000250|UniProtKB:O16000}.
CC -!- SUBUNIT: Interacts with unc-18. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Single-pass type IV
CC membrane protein {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the syntaxin family. {ECO:0000305}.
