UniProt Summary: Intracellular orphan receptor that binds numerous drugs and which is highly expressed in various proliferating cancer cells (PubMed:28559337). Corresponds to the sigma-2 receptor, which is thought to play important role in regulating cell survival, morphology and differentiation (PubMed:23922215, PubMed:25620095). Under investigation for its potential diagnostic and therapeutic uses (PubMed:23922215, PubMed:25620095). May play a role as a regulator of cellular cholesterol homeostasis (PubMed:19583955). May function as sterol isomerase (PubMed:25566323). May alter the activity of some cytochrome P450 proteins (PubMed:22292588). {ECO:0000269|PubMed:19583955, ECO:0000269|PubMed:28559337, ECO:0000303|PubMed:22292588, ECO:0000303|PubMed:23922215, ECO:0000303|PubMed:25620095, ECO:0000305|PubMed:25566323}.
