    SUBCELLULAR LOCALIZATION     intracellular
    text nuclear signaling protein
    basic FUNCTION
  • activating the RAS and JUN kinase signaling pathways
  • transforming fibroblasts in a RAS-dependent fashion
  • adapter protein functioning in signal transduction, best known as a substrate of the BCR-ABL kinase in chronic myelogenous leukemia
  • playing a role in fibroblast transformation by BCR-ABL
  • may mediate the transduction of intracellular signals
  • permits cells to bypass the strict need for adhesion in response to FGF8 through direct interaction with receptor
  • 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
  • regulates head and neck squamous cell carcinoma-cell growth, motility, and integrin-dependent cell adhesion, suggesting that CRKL plays a principal role in HNSCC tumorigenicity
  • significant role for CRKL in regulating cell motility
  • has the ability to regulate gastric cell proliferation
  • involved in signal transduction from multiple tyrosine kinase receptors
  • cytoskeletal adaptor protein , having crucial roles in multiple biological processes, including cell proliferation, adhesion, and migration
  • CELLULAR PROCESS cell communication
  • heart development
  • organ morphogenesis
  • parathyroid gland development
  • thymus development
    signaling signal transduction
  • JNK cascade
  • intracellular signaling cascade
  • CRKL-MAPK pathway might be important in human cardiac development and disease
  • a component
    small molecule
  • interacting with INPP5D/SHIP1
  • interacting with DOCK2 and EPOR
  • interacting with phosphorylated CBLB
  • specific interaction between phosphorylated Y463 in FGFR1 with the CRKL SH2 domain
  • Sprouty1 and Sprouty2 bind to the adaptor protein CRKL in a stimulus-dependent manner (Satoh 2010)
  • with CRK have been proposed to interact with tyrosine phosphorylated DAB1 to mediate downstream events in the Reelin pathway
  • interaction with CRK, and DOK7 (critical role for CRK and CRKL downstream from DOK7 in presynaptic and postsynaptic differentiation)(
  • association of ESR1 and CRKL directly enhances the tumorigenic potential of CRKL, thus pointing to its role in cell proliferation
  • CRKL adaptor protein associating with PTPN6 (association is due to CRKL binding to PxxP domains located at AA residues 158-161 within the PTPN6 C-terminal SH2 domain, and AA residues 363-366 within its phosphatase domain)
  • CRKL signaling was associated with SRC family kinase (SFK) signaling, specifically with YES1 kinase
  • promotes CASP8 recruitment to the peripheral spreading edge of cells, and that the catalytic domain of CASP8 directly interacts with the SH2 domain of CRKL
  • DOK1 adaptor is the key effector for the enhancement of CRKL transformation by ABLinhibition
