RL Cell. Signal. 13:51-55(2001).
CC -!- FUNCTION: Adapter protein that provides a critical link between cell
CC surface growth factor receptors and the Ras signaling pathway (By
CC similarity). Promotes meiotic reinitiation during oocyte maturation.
CC {ECO:0000250, ECO:0000269|PubMed:11257447}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.
CC Endosome {ECO:0000250}. Golgi apparatus {ECO:0000250}.
CC -!- DOMAIN: The two SH3 domains and the SH2 domain are necessary for the
CC reinitiation of oocyte meiosis. {ECO:0000269|PubMed:11257447}.
