Functioni

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.By similarity

Miscellaneous

It may cross-link plasma membrane phospholipids with actin and the cytoskeleton and be involved with exocytosis.
