DESCRIPTION

Also known as SHC1_HUMAN, SHC1, SHC, SHCA. Signaling adapter that couples activated growth factor receptors to signaling pathways. Participates in a signaling cascade initiated by activated KIT and KITLG/SCF. Isoform p46Shc and isoform p52Shc, once phosphorylated, couple activated receptor tyrosine kinases to Ras via the recruitment of the GRB2/SOS complex and are implicated in the cytoplasmic propagation of mitogenic signals. Isoform p46Shc and isoform p52Shc may thus function as initiators of the Ras signaling cascade in various non-neuronal systems. Isoform p66Shc does not mediate Ras activation, but is involved in signal transduction pathways that regulate the cellular response to oxidative stress and life span. Isoform p66Shc acts as a downstream target of the tumor suppressor p53 and is indispensable for the ability of stress-activated p53 to induce elevation of intracellular oxidants, cytochrome c release and apoptosis. The expression of isoform p66Shc has been correlated with life span (By similarity). Participates in signaling downstream of the angiopoietin receptor TEK/TIE2, and plays a role in the regulation of endothelial cell migration and sprouting angiogenesis. Interacts with CPNE3; this interaction may mediate the binding of CPNE3 with ERBB2 (PubMed:20010870). Interacts with the NPXY motif of tyrosine-phosphorylated IGF1R and INSR in vitro via the PID domain. Once activated, binds to GRB2. Interacts with tyrosine-phosphorylated CD3T and DDR2. Interacts with the N-terminal region of SH2B2. Interacts with phosphorylated LRP1 and IRS4. Interacts with INPP5D/SHIP1 and INPPL1/SHIP2. Interacts with TRIM31. Interacts with PTPN6/SHP (tyrosine phosphorylated). Identified in a complex containing FGFR4, NCAM1, CDH2, PLCG1, FRS2, SRC, SHC1, GAP43 and CTT (By similarity). Interacts with ALK, GAB2, GRB7 and KIT. Interacts with FLT4 (tyrosine-phosphorylated). Interacts with EPHB1 and GRB2; activates the MAPK/ERK cascade to regulate cell migration. Interacts with PDGFRB (tyrosine-phosphorylated). Interacts with ERBB4. Interacts with TEK/TIE2 (tyrosine-phosphorylated). Interacts with the Trk receptors NTRK1, NTRK2 and NTRK3; in a phosphotyrosine-dependent manner. Interacts with PTK2/FAK1. Interacts with CEACAM1; this interaction is CEACAM1-phosphorylation-dependent and mediates interaction with EGFR or INSR resulting in decrease coupling of SHC1 to the MAPK3/ERK1-MAPK1/ERK2 pathway (By similarity). Interacts (via PID domain) with PEAK1 (when phosphorylated at 'Tyr-1188') (PubMed:23846654). Found in a complex with PPP1CA, PPP1CC, SHC1 and PEAK1 (PubMed:23846654).
