Rabbit Anti-Scavenger Receptor BII/FITC Conjugated antibody
background:
High density lipoproteins (HDLs) play a critical role in cholesterol metabolism and their plasma concentrations are inversely correlated with risk for atherosclerosis. SR-BI and SR-BII (previously known as SR-BI.2) are the alternatively spliced products of a single gene. SR-BII and SR-BI are identical except for the encoded c-terminal cytoplasmic domain. Both SR-BI and SR-BII bind HDL and mediates selective uptake of HDL cholesteryl ester, but with SR-BII having an approximately 4-fold lower efficiency than SR-BI. SR-BI and SR-BII are expressed primarily in liver and non-placental steroidgenic tissues. Although the role of these scavenger receptors is not completely clear, SR-BII mRNA results from the alternative splicing of SR-BI precursor transcripts with both isoforms mediating selective transfer of lipid between HDL and cells. Therefore, the relative expression and functional activities of these two isoforms create a potential means of regulating selective lipid transfer between HDL and cells.
Function:
Acts as a lysosomal receptor for glucosylceramidase (GBA) targeting.
Subunit:
Interacts with GBA (via the coiled-coil domain).
Subcellular Location:
Lysosome membrane; Multi-pass membrane protein.
DISEASE:
Defects in SCARB2 are the cause of progressive myoclonic epilepsy type 4 with or without renal failure (EPM4) [MIM:25980]. An autosomal recessive progressive myoclonic epilepsy associated with renal failure in some cases. Cognitive function is preserved. Myoclonus is a brief, involuntary twitching of a muscle or a group of muscles. Cognitive function is preserved.
Note=Genetic variants in SCARB2 can act as modifier of the phenotypic expression and severity of Gaucher disease.
Similarity:
Belongs to the CD36 family.
