Each AP-2 heterotetramer is composed of α, β, μ, and σ protein subunits. The 50 kDa μ subunit (AP-2μ, AP2M1) is located at the core of the AP-2 complex and mediates interaction between the cargo protein and the clathrin-coated pit (1-4). The carboxy-terminal AP2M1 region recognizes the tyrosine-based, endocytotic sorting motif YXXφ found in cargo proteins and helps to bring the cargo protein to the clathrin-coated pit. Non-canonical, tyrosine-based endocytotic sorting signals can also promote interaction between cargo proteins and AP2M1 (5,6). AP2M1 plays an essential role in molecular signaling as it couples receptor-mediated endocytosis and pathways involving membrane receptors (7-9), matrix metalloproteinases (10), and ion channel proteins (11). Phosphorylation of specific AP2M1 residues and binding of lipids to this adaptor protein can regulate AP2M1 activity (12,13). Phosphorylation of AP2M1 at Thr156 by adaptor-associated kinase 1 (AAK1) stimulates affinity binding of AP2M1 to cargo protein signals (14).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nAdapter-related protein complex 2 mu subunit; Adaptin-mu2; Adaptor protein complex AP-2 subunit mu; adaptor related protein complex 2 mu 1 subunit; adaptor related protein complex 2 subunit mu 1; Adaptor-related protein complex 2 subunit mu; adaptor-related protein complex 2, mu 1 subunit; AP-2 complex subunit mu; AP-2 mu 2 chain; AP-2 mu chain; AP-2 mu2; AP2M1; AP50; CLAPM1; clathrin adaptor complex AP2, mu subunit; Clathrin assembly protein complex 2 medium chain; Clathrin assembly protein complex 2 mu medium chain; clathrin coat adaptor protein AP50; Clathrin coat assembly protein AP50; Clathrin coat-associated protein AP50; clathrin-associated\/assembly\/adaptor protein, medium 1; HA2 50 kDa subunit; KIAA0109; MRD60; mu2; Plasma membrane adaptor AP-2 50 kDa protein; plasma membrane adaptor AP-2 50kDA protein\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M\nSENSITIVITY: Endogenous\nMW (kDa): 50\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799462629545,"sku":"3843S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3843s","provider":"Iright","version":"1.0","type":"link"}
