Predicted to enable DNA binding activity and metal ion binding activity. Involved in negative regulation of Ras protein signal transduction; negative regulation of vulval development; and regulation of cell fate specification. Predicted to be located in nucleus. Is expressed in several structures, including anal region; germ line; head muscle; oocyte; and somatic cell.
WB Description
lin-15B encodes a novel protein that contains a THAP domain, a zinc-coordinating, site-specific DNA-binding domain; lin-15B was first identified as a class B synMuv gene that acts redundantly with lin-15A to negatively regulate the outcome of Ras signaling during vulval cell fate specification; subsequently, lin-15B has been shown to also negatively regulate progression through the G1 phase of the cell cycle and RNA-mediated interference (RNAi).
