Summary: Predicted to enable several functions, including C-acyltransferase activity; anion binding activity; and lipid transfer activity. Involved in fatty acid derivative biosynthetic process; fatty acid metabolic process; and regulation of phospholipid biosynthetic process. Located in endoplasmic reticulum; mitochondrion; and peroxisome. Is expressed in several structures, including central nervous system; hair follicle; intestine; liver; and retina layer. Orthologous to human SCP2 (sterol carrier protein 2). [provided by Alliance of Genome Resources, Apr 2025]

Both FABP1 and SCP-2 participate in regulating the Brain endocannabinoids (EC) system in the brain.
Title: Sterol Carrier Protein-2/Sterol Carrier Protein-x/Fatty Acid Binding Protein-1 Ablation Impacts Response of Brain Endocannabinoid to High-Fat Diet.
These findings suggested that ablation of the Scp-2/Scp-x gene in Fabp1 null mice exacerbated hepatic endocannabinoid (EC) accumulation and antagonized the impact of high fat diet on hepatic EC levels-suggesting both proteins play important roles in regulating the hepatic EC system.
Title: Scp-2/Scp-x ablation in Fabp1 null mice differentially impacts hepatic endocannabinoid level depending on dietary fat.
These results indicate an important regulatory role for SCP2 deficiency in attenuating diet-induced atherosclerosis by limiting intestinal cholesterol absorption and decreasing hepatic triglyceride/VLDL secretion.
Title: Sterol carrier protein-2 deficiency attenuates diet-induced dyslipidemia and atherosclerosis in mice.
Ablating both Fabp1 and Scp2/Scpx (TKO) induces hepatic phospholipid and cholesterol accumulation in high fat-fed mice

role of Fabp1/Scp-2 in hepatic phytol metabolism
Title: Impact of Fabp1/Scp-2/Scp-x gene ablation (TKO) on hepatic phytol metabolism in mice.
Thus, the loss of Scp-2/Scp-x contributed to a sex-dependent hepatic accumulation of dietary phytol and BCFA.
Title: Sex-dependent impact of Scp-2/Scp-x gene ablation on hepatic phytol metabolism.
Individually ablating SCPx or SCP2/SCPx elicited concomitant upregulation of L-FABP.
Title: Impact of dietary phytol on lipid metabolism in SCP2/SCPX/L-FABP null mice.
Lack of a significant decrease in the flux of HDL-[(3)H]CE to biliary FC or bile acids in FABP1(-/-) mice indicates the likely compensation of its function by an as yet unidentified mechanism. Taken together, these studies demonstrate that FABP1 and SCP2 facilitate the preferential movement of HDL-CEs to bile for final elimination
Title: Intracellular cholesterol transport proteins enhance hydrolysis of HDL-CEs and facilitate elimination of cholesterol into bile.

L-FABP was more important in hepatic retention of bile acids, while SCP-2/SCP-x more broadly affected biliary bile acid and phospholipid levels.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
