Protein: Probable serine/threonine-protein phosphatase PP2A regulatory subunit (Protein phosphatase PP2A regulatory subunit A) (Q09543)
Organism: Caenorhabditis elegans
Function: Acts as a scaffolding protein for phosphatase let-92 and its regulatory subunits (Probable). Probably together with let-92 and regulatory subunit sur-6, regulates centriole duplication, microtubule outgrowth and mitotic spindle stability during early embryonic cell division by preventing the degradation of sas-5 and kinase zyg-1. During vulva development, may play a role with phosphatase let-92 and regulatory subunit sur-6 in the induction of vulva cell precursors by positively regulating let-60/Ras-MAP kinase signaling, probably by promoting lin-45 activation. Plays a positive role in axon guidance probably by inhibiting phosphatase let-92.
