Both proteins are widely expressed and contain an amino-terminal kinase domain followed by a central proline\/serine rich domain and a highly conserved carboxy-terminal domain. The roles of ULK1 and ULK2 in axon growth have been linked to studies showing that the kinases are localized to neuronal growth cones and are involved in endocytosis of critical growth factors, such as NGF (5). Yeast two-hybrid studies found ULK1\/2 associated with modulators of the endocytic pathway, SynGAP, and syntenin (6). Structural similarity of ULK1\/2 has also been recognized with the yeast autophagy protein Atg1\/Apg1 (7). Knockdown experiments using siRNA demonstrated that ULK1 is essential for autophagy (8), a catabolic process for the degradation of bulk cytoplasmic contents (9,10). It appears that Atg1\/ULK1 can act as a convergence point for multiple signals that control autophagy (11), and can bind to several autophagy-related (Atg) proteins, regulating phosphorylation states and protein trafficking (12-16).~AMPK, activated during low nutrient conditions, directly phosphorylates ULK1 at multiple sites including Ser317, Ser555, and Ser777 (17,18). Conversely, mTOR, which is a regulator of cell growth and is an inhibitor of autophagy, phosphorylates ULK1 at Ser757 and disrupts the interaction between ULK1 and AMPK (17).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nATG1; ATG1 autophagy related 1 homolog; ATG1A; Autophagy-related protein 1 homolog; FLJ38455; FLJ46475; hATG1; KIAA0722; Serine\/threonine-protein kinase ULK1; ULK1; unc-51 like autophagy activating kinase 1; Unc-51-like kinase 1; unc-51-like kinase 1 (C. elegans); UNC51; Unc51.1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800373350569,"sku":"29313S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-29313s","provider":"Iright","version":"1.0","type":"link"}
