Recombinant Human Autophagy-related protein 2 homolog B (ATG2B), Truncated

Uniprot Id

Q96BY7

Target Species

Human

Target Name

ATG2B

Target Full Name

Autophagy-related protein 2 homolog B

Target Function

Lipid transfer protein required for both autophagosome formation and regulation of lipid droplet morphology and dispersion. Tethers the edge of the isolation membrane (IM) to the endoplasmic reticulum (ER) and mediates direct lipid transfer from ER to IM for IM expansion. Binds to the ER exit site (ERES), which is the membrane source for autophagosome formation, and extracts phospholipids from the membrane source and transfers them to ATG9 (ATG9A or ATG9B) to the IM for membrane expansion. Lipid transfer activity is enhanced by WDR45/WIPI4, which promotes ATG2B-association with phosphatidylinositol 3-monophosphate (PI3P)-containing membranes.

Target Subcellular Location

Preautophagosomal structure membrane; Peripheral membrane protein. Lipid droplet. Endoplasmic reticulum membrane; Peripheral membrane protein.

Target Background

This gene encodes a protein required for autophagy. The encoded protein is involved in autophagosome formation. A germline duplication of a region that includes this gene is associated with predisposition to myeloid malignancies.
