Component of a complex comprised of SH2D3C, BCAR1/CAS, and CRK (PubMed:12432078). Within the complex, interacts with SH2D3C (via C-terminus), and BCAR1/CAS (PubMed:12432078). Found in a complex with ABL1, ABL2, CRK and UNC119; leading to the inhibition of CRK phosphorylation by ABL kinases (PubMed:19381274). Interacts with ABL1, C3G, DOCK3, DOCK5, MAP4K1, MAPK8 and SOS via its first SH3 domain. Interacts (via SH2 domain) with BCAR1, CBL, CBLB, PXN, IRS4 and GAB1 upon stimulus-induced tyrosine phosphorylation. Interacts (via SH2 domain) with several tyrosine-phosphorylated growth factor receptors such as EGFR and INSR. Interacts with FLT1 (tyrosine-phosphorylated). Interacts with DOCK1 and DOCK4. Interacts with SHB. Interacts with PEAK1. Interacts with FASLG. Part of a collagen stimulated complex involved in cell migration composed of CDC42, CRK, TNK2 and p130cas/BCAR1. Interacts (via SH2 domain) with the 'Tyr-9' phosphorylated form of PDPK1. Interacts with CBLC. [Isoform Crk-II]: Interacts (via SH2 domain) with PDGFRA (tyrosine phosphorylated) and PDGFRB (tyrosine phosphorylated) (PubMed:10733900). Interacts with EPHA3 (phosphorylated); upon activation of EPHA3 by the ligand EFNA5 and EPHA3 tyrosine kinase activity-dependent and mediates EFNA5-EPHA3 signaling through RHOA GTPase activation (PubMed:11870224). Interacts with KIT (PubMed:12878163). Interacts with PEAK3; the interaction requires PEAK3 homodimerization (PubMed:31311869).
