ATG9B Protein, Human (HEK293, FLAG)

ATG9B Protein, a phospholipid scramblase crucial for autophagy, dynamically cycles between the preautophagosomal structure (PAS) and the cytoplasmic vesicle pool. It plays a critical role in expanding autophagosomal membranes, facilitating lipid distribution with ATG2 and driving membrane expansion. Additionally, ATG9B participates in necrotic cell death. ATG9B Protein, Human (HEK293, FLAG) is the recombinant human-derived ATG9B protein, expressed by HEK293 , with C-Flag labeled tag. The total length of ATG9B Protein, Human (HEK293, FLAG) is 924 a.a., .

ATG9B Protein functions as a phospholipid scramblase crucially involved in autophagy, mediating the expansion of autophagosomal membranes. It dynamically cycles between the preautophagosomal structure/phagophore assembly site (PAS) and the cytoplasmic vesicle pool, acting as a critical supplier of membranes for the growing autophagosome. The lipid scramblase activity of ATG9B is pivotal in the preautophagosomal structure/phagophore assembly process, facilitating the distribution of phospholipids arriving through ATG2 (either ATG2A or ATG2B) from the cytoplasmic leaflet to the luminal leaflet of the bilayer. This activity, in turn, drives the expansion of autophagosomal membranes. Beyond its role in autophagy, ATG9B also participates in necrotic cell death.
