Description_x000D_ Immunogen_x000D_ Peptide sequence around phosphorylation site of tyrosine 427 (P-S-Y(p)-V-N, according to the protein SHC1._x000D_ Target description_x000D_ Signaling adapter that couples activated growth factor receptors to signaling pathway. 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._x000D_ Physical form_x000D_ Solution in phosphate-buffered saline containing 0.02% sodium azide and 50% glycerol_x000D_ Features and Benefits_x000D_ Evaluate our antibodies with complete peace of mind.
