UBASH3B is a modular protein that contains an N-terminal UBA domain that can interact with ubiquitin, a central SH3 domain that mediates protein-protein interactions, and an evolutionarily conserved C-terminal phosphatase domain. Indeed, research studies have shown that UBASH3B interacts with Bcr-Abl and negatively regulates its kinase activity through a mechanism involving dephosphorylation (1). UBASH3B also plays a pivotal role in the adaptive immune response by negatively regulating the activity of key proximal signaling proteins downstream of the T cell receptor (TCR) (2-4). Research studies have also positioned UBASH3B as an oncogenic protein in the context of triple-negative breast cancer, where its overexpression promotes enhanced EGFR stability via protection from c-Cbl-mediated ubiquitination (5,6).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCbl-interacting protein p70; Cbl-interacting protein Sts-1; KIAA1959; MGC15437; nm23-phosphorylated unknown substrate; p70; SH3 domain-containing 70 kDa protein, suppressor of T-cell receptor signaling 1, nm23-phosphorylated unknown substrate; STS-1; STS1; Suppressor of T-cell receptor signaling 1; T-cell ubiquitin ligand 2; TULA-2; TULA2; Tyrosine-protein phosphatase STS1\/TULA2; UBASH3B; ubiquitin associated and SH3 domain containing B; ubiquitin associated and SH3 domain containing, B; Ubiquitin-associated and SH3 domain-containing protein B; UBS3B\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 70\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46798014808233,"sku":"27599T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-27599t","provider":"Iright","version":"1.0","type":"link"}
