Most members contain an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain. This gene has been shown to be imprinted, with preferential expression from the maternal allele only in placenta. Transcript variants encoding different isoforms have been identified. [provided by RefSeq, Oct 2010]. * **UniProt Summary**: Lipid transporter involved in lipid countertransport between the endoplasmic reticulum and the plasma membrane: specifically exchanges phosphatidylserine with phosphatidylinositol 4-phosphate (PI4P), delivering phosphatidylserine to the plasma membrane in exchange for PI4P, which is degraded by the SAC1/SACM1L phosphatase in the endoplasmic reticulum. Binds phosphatidylserine and PI4P in a mutually exclusive manner (PubMed:23934110, PubMed:26206935). May cooperate with NPC1 to mediate the exit of cholesterol from endosomes/lysosomes (PubMed:21220512). Binds 25-hydroxycholesterol and cholesterol (PubMed:17428193). {ECO:0000269|PubMed:17428193, ECO:0000269|PubMed:21220512, ECO:0000269|PubMed:23934110, ECO:0000269|PubMed:26206935}. |PH| |Oxysterol BP| |phosphatidylserine transfer activity| |oxysterol binding| |endoplasmic reticulum-plasma membrane contact site| |sterol binding| |sterol transporter activity| |phospholipid transporter activity| |phosphatidylserine acyl-chain remodeling| |phosphatidylinositol-4-phosphate binding| |phosphatidylserine metabolic process| |cholesterol binding| |cholesterol transport| |phosphatidylserine binding| |Golgi to plasma membrane transport| |sterol transport| |phospholipid transport| |vesicle-mediated transport to the plasma membrane| |post-Golgi vesicle-mediated transport| |cholesterol metabolic process| |organophosphate ester transport| |secondary alcohol metabolic process| |sterol metabolic process| |organic hydroxy compound transport| |lipid binding| |cellular modified amino acid metabolic process| |steroid metabolic process| |lipid transport| |glycerophospholipid metabolic process| |alcohol metabolic process| |lipid localization| |Golgi vesicle transport| |phospholipid metabolic process| |glycerolipid metabolic process| |organic hydroxy compound metabolic process| |organic anion transport| |anion transport| |intracellular membrane-bounded organelle| |organophosphate metabolic process| |endoplasmic reticulum membrane| |cellular lipid metabolic process| |lipid metabolic process| |ion transport| |small molecule metabolic process| |vesicle-mediated transport| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp159|Docetaxel 0.001 to 0.002μM on day4 R04 exp159]]|-1.9| |[[:results:exp185|L-BMAA 500 to 750μM on day4 R04 exp185]]|-1.7| |[[:results:exp538|ZLN024 50μM R08 exp538]]|1.89| No correlation found to any other genes in chemogenomics.
