Research studies have shown that Gab2 is a widely expressed protein that participates in orchestrating signals downstream of many transmembrane receptors for growth factors and cytokines (2). Indeed, Gab2 was initially identified as a tyrosine-phosphorylated protein associated with SHP-2 and the p85 subunit of PI3K in response to engagement of the IL-3 and M-CSF receptors (3,4). Subsequent studies also identified Gab2 as a participant in signaling cascades triggered by the T cell antigen receptor (5,6). It is now well established that Gab2 is a critical component of signaling cascades triggered by numerous oncogenic tyrosine kinases. In the context of human disease, Gab2 is overexpressed in breast cancer and ovarian cancer, which facilitates tumor cell proliferation and survival (7,8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nGAB2; GRB2 associated binding protein 2; GRB2-associated binder 2; GRB2-associated binding protein 2; GRB2-associated-binding protein 2; Growth factor receptor bound protein 2-associated protein 2; KIAA0571; pp100\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 90\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799919644841,"sku":"80884S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-80884s","provider":"Iright","version":"1.0","type":"link"}
