    text
  • colocolizing with DOCK1 and ELMO1 to membrane ruffles
  • significant percentage of the total endogenous CRK partitions in the nucleus in mammalian cells, where it forms distinct complexes with DOCK1, WEE1, and ABL1
  • basic FUNCTION
  • adaptor protein, involved in cell growth and motility
  • involved in phagocytosis of apoptotic cells and cell motility via its interaction with DOCK1 and DOCK4
  • playing a crucial role in the aggressiveness of human synovial sarcoma
  • play a critical role in the breakdown of adherens junctions and the spreading of sheets of epithelial cells
  • have both cytosolic and nuclear functions
  • its nuclear compartmentalization antagonizes its cytoskeletal functions and assign a proapoptotic role to the nuclear pool of CRK
  • effector molecule for Rac1 activation that regulates cell motility
  • regulates cell migration, morphogenesis, invasion, phagocytosis, and survival
  • CRK and CRKL adaptor proteins play important roles in numerous signaling pathways, bridging tyrosine kinase substrates to downstream signaling effectors by virtue of their phosphotyrosine-binding SH2 domains and their effector-binding SH3 domains
  • CRK-MYO1C interaction, which modulates membrane dynamics by regulating RAC1 activity, is crucial for cell adhesion and spreading
  • CRK and CRKL have overlapping functions that are critical for maintaining cell structure and have critical roles in cell structure and motility by maintaining cytoskeletal integrity 0)
  • CRK, CRKL were required for effector T cell trafficking into sites of inflammation, but not for migration to lymphoid organs
  • CRK and CRKL play essential overlapping roles in fibroblast growth
  • CRK and CRKL play overlapping roles downstream of FGF signaling in order to regulate lens fiber cell elongation

    protein
  • binding to GRB2, ELMO1
  • activating RAC1
  • interacting with PAFAH1B1
  • SH2-SH3 adaptor protein CRK is an essential target of GIT2 inhibition
  • with CRKL have been proposed to interact with tyrosine phosphorylated DAB1 to mediate downstream events in the Reelin pathway
  • interaction with DOK7, and CRKL (critical role for CRK and CRKL downstream from DOK7 in presynaptic and postsynaptic differentiation)(
  • interaction with SOS1 (have a surprising negative role for ABL kinases in CRK transformation)
  • cell & other
