Protein Name:
Vesicle-associated membrane protein-associated protein B
|
UniprotKB/SwissProt ID: Q9QY76 (Q9QY76)
Gene Name:
Vapb
Organism: Mus musculus (Mouse)
Function: Endoplasmic reticulum (ER)-anchored protein that mediates the formation of contact sites between the ER and endosomes via interaction with FFAT motif-containing proteins such as STARD3 or WDR44. Interacts with STARD3 in a FFAT motif phosphorylation dependent manner. Via interaction with WDR44 participates in neosynthesized protein export. Participates in the endoplasmic reticulum unfolded protein response (UPR) by inducing ERN1/IRE1 activity. Involved in cellular calcium homeostasis regulation
