  Function in Host
Calcium-regulated membrane-binding protein whose affinity forcalcium is greatly enhanced by anionic phospholipids. It binds twocalcium ions with high affinity. May be involved in heat-stressresponse. Inhibits PCSK9-enhanced LDLR degradation, probably reducesPCSK9 protein levels via a translational mechanism but also competeswith LDLR for binding with PCSK9. [1-3]
