Protein Structure

UniProt Annotation

Function

Mediates in vitro the transfer of all common phospholipids, cholesterol and gangliosides between membranes. May play a role in regulating steroidogenesis. {ECO:0000269PubMed:17157249, ECO:0000269PubMed:8300590}.

Subcellular Localization

Cytoplasm {ECO:0000269PubMed:17157249}. Mitochondrion {ECO:0000269PubMed:17157249}. Note=Cytoplasmic in the liver and also associated with mitochondria especially in steroidogenic tissues.Isoform SCPx: Peroxisome. Note=Interaction with PEX5 is essential for peroxisomal import.Isoform SCP2: Mitochondrion {ECO:0000305}.

Disease Associations

Leukoencephalopathy, with dystonia and motor neuropathy (LDMN) [MIM:613724]: A syndrome characterized by leukoencephalopathy, dystonic head tremor, spasmodic torticollis and reduced tendon reflexes in lower extremities. Additional features include hyposmia, pathologic saccadic eye movements, a slight hypoacusis, accumulation of branched-chain pristanic acid in plasma, and the presence of abnormal bile alcohol glucuronides in urine. {ECO:0000269PubMed:16685654}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Liver, fibroblasts, and placenta.
