It contains an amino-terminal LC3-interacting region (LIR) that is responsible for associating with LC3 and recruiting mitochondria to the autophagosome. The phosphorylation state of FUNDC1 can regulate its activity by affecting its binding to LC3 (4-6). Under normal conditions, FUNDC1 is phosphorylated at Tyr18 by Src, which is inhibited during hypoxia, leading to dephosphorylation (4). FUNDC1 activity is also inhibited by phosphorylation by CK2 at Ser13, which is overcome during hypoxia by the phosphatase PGAM5 which dephosphorylates this site (5). Furthermore, the autophagy kinase ULK1 phosphorylates FUNDC1 at Ser17 which enhances binding to LC3 (6). The levels of FUNDC1 can also be tightly regulated through the ubiquitin\/proteasome pathway via the E3 ligase MARCH5, which targets FUNDC1 for degradation (7).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nFUN14 domain containing 1; FUN14 domain-containing protein 1; FUND1; FUNDC1; MGC51029\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 17\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799685976233,"sku":"49240T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-49240t","provider":"Iright","version":"1.0","type":"link"}
