Caenorhabditis elegans


CELE_R186.4, R186.4
lin-46 encodes one of two C. elegans paralogs of bacterial MoeA proteins and mammalian gephyrins (E domain, only); LIN-46 is predicted to function as a scaffolding protein for a developmental timing complex, and may also play a role in molybdenum cofactor biosynthesis; identified in screens for suppressors of precocious heterochronic mutations in lin-14 and lin-28, lin-46 is required for stage-specific developmental events at the third larval and adult stages of development; as a component of the heterochronic pathway, lin-46 appears to act immediately downstream of lin-28, which encodes a pre-miRNA binding protein required for cell fate specification at the L2 stage; a LIN-46:GFP fusion protein is detected in the cytoplasm and non-nucleolar part of the nucleus of ventral and lateral hypodermal cells around the time of the larval molts; in addition, the LIN-46 fusion protein is detected in cell bodies and axons of the AVBL/R motor interneurons.
