UBASH3A 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 a C-terminal histidine phosphatase domain (1,2). Although it displays limited phosphatase activity compared to its homolog UBASH3B, UBASH3A functions as a negative regulator of T cell activation by downregulating the TCR-CD3 complex in a phosphatase-independent manner (3). UBASH3A also associates with the E3 ubiquitin ligase Cbl-b, which further dampens T cell activation through downregulation of CD28 (3). Due to its role in regulating T cell responses, UBASH3A dysfunction has been linked to several autoimmune disorders, including type 1 diabetes, rheumatoid arthritis, celiac disease, and systemic lupus erythematosus (4-7).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCbl-interacting protein 4; CLIP4; STS-2; STS2; Suppressor of T-cell receptor signaling 2; T-cell ubiquitin ligand; T-cell ubiquitin ligand 1; T-cell ubiquitin ligand protein; TULA; TULA-1; UBASH3A; ubiquitin associated and SH3 domain containing A; ubiquitin associated and SH3 domain containing, A; Ubiquitin-associated and SH3 domain-containing protein A; UBS3A\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 74, 80\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799488123049,"sku":"41606T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-41606t","provider":"Iright","version":"1.0","type":"link"}
