Description
Description: Calcium-regulated membrane-binding protein whose affinity for calcium is greatly enhanced by anionic phospholipids. It binds two calcium ions with high affinity. May be involved in heat-stress response. Inhibits PCSK9-enhanced LDLR degradation, probably reduces PCSK9 protein levels via a translational mechanism but also competes with LDLR for binding with PCSK9 (PubMed:18799458, PubMed:24808179, PubMed:22848640).
Post Translational Modifications: Phosphorylation of Tyr-24 enhances heat stress-induced translocation to the cell surface. ISGylated.
Subunit Structure: Heterotetramer containing 2 light chains of S100A10/p11 and 2 heavy chains of ANXA2/p36 (By similarity). Interacts with ATP1B1 (By similarity). Interacts with DYSF (By similarity). Interacts with COCH (PubMed:21886777). Interacts (via repeat Annexin 1) with PCSK9 (via the C-terminal domain); the interaction inhibits the degradation of LDLR (PubMed:18799458). Interacts with CEACAM1 (via the cytoplasmic domain); this interaction is regulated by phosphorylation of CEACAM1 (PubMed:14522961).
Similarity: A pair of annexin repeats may form one binding site for calcium and phospholipid. Belongs to the annexin family
