{"product_id":"abm213956","title":"Human Golgin Subfamily A Member 2, GOLGA2 ELISA Kit","description":"\u003ch3\u003eBackground\u003c\/h3\u003e\u003cp\u003ePeripheral membrane component of the cis-Golgi stack that acts as a membrane skeleton that maintains the structure of the Golgi apparatus, and as a vesicle thether that facilitates vesicle fusion to the Golgi membrane (Probable) (PubMed: 16489344). Required for normal protein transport from the endoplasmic reticulum to the Golgi apparatus and the cell membrane (By similarity). Together with p115\/USO1 and STX5, involved in vesicle tethering and fusion at the cis-Golgi membrane to maintain the stacked and inter-connected structure of the Golgi apparatus. Plays a central role in mitotic Golgi disassembly: phosphorylation at Ser-37 by CDK1 at the onset of mitosis inhibits the interaction with p115\/USO1, preventing tethering of COPI vesicles and thereby inhibiting transport through the Golgi apparatus during mitosis (By similarity). Also plays a key role in spindle pole assembly and centrosome organization (PubMed: 26165940). Promotes the mitotic spindle pole assembly by activating the spindle assembly factor TPX2 to nucleate microtubules around the Golgi and capture them to couple mitotic membranes to the spindle: upon phosphorylation at the onset of mitosis, GOLGA2 interacts with importin-alpha via the nuclear localization signal region, leading to recruit importin-alpha to the Golgi membranes and liberate the spindle assembly factor TPX2 from importin-alpha. TPX2 then activates AURKA kinase and stimulates local microtubule nucleation. Upon filament assembly, nascent microtubules are further captured by GOLGA2, thus linking Golgi membranes to the spindle (PubMed: 19242490, PubMed: 26165940). Regulates the meiotic spindle pole assembly, probably via the same mechanism (By similarity). Also regulates the centrosome organization (PubMed: 18045989, PubMed: 19109421). Also required for the Golgi ribbon formation and glycosylation of membrane and secretory proteins (PubMed: 16489344, PubMed: 17314401).\u003c\/p\u003e","brand":"BT LAB","offers":[{"title":"48T","offer_id":57661801759060,"sku":"ABM213956","price":205.0,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":57661801791828,"sku":"ABM213957","price":293.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/btlab-69e4cf544ed9bd0f5a8a0d03a4c0a5f6ed34681dc79755ada59dedd1012c9284.jpg?v=1792159241","url":"https:\/\/www.abmium.com\/fr\/products\/abm213956","provider":"ABMIUM","version":"1.0","type":"link"}
