lin-56 encodes a novel protein that contains a THAP zinc-finger-like domain; lin-56, along with lin-15A, which also encodes a THAP domain-containing protein, functions as a transcriptional regulator to negatively regulate expression of LIN-3/EGF and, in turn, Ras-mediated vulval development; LIN-56 is expressed ubiquitously in somatic cells from embryogenesis through adulthood and localizes to nuclei; LIN-56 and LIN-15A physically interact in a yeast two-hybrid assay and are mutually required for normal patterns of expression.
Involved in several processes, including protein localization to nucleus; protein stabilization; and vulval development. Located in nucleus. Expressed in somatic cell.
