Background SR-BI (scavenger receptor class BI, SCARB1) is a member of CD36 receptor family and act as a major receptor for HDL for facilitating selective lipid uptake from lipoproteins in several tissues. SR-BI gene gives rise to at least two mRNA splice variants (SR-BI and SR-BII), and interestingly, SR-BII variant is the main isoform in terms of mRNA levels in certain tissues e.g. SR-BII mRNA is 48-fold higher than SR-BI in brain cells; and protein levels reaching 10-15% of SR-BI in the liver. Similar differential SR-BII protein expression levels have also been detected in considerable amounts in other tissues, such as testes, retinal pigment epithelial cells, and spleen. SR-BII isoform differs from SR-BI only in its entirely different, yet highly conserved, cytoplasmic C-terminus which has been proposed to contains a signal responsible for marked alterations in cellular distribution as well as cellular trafficking of SR-BII compared with SR-BI. In contrast to SR-BI, SR-BII mediates the rapid uptake of significant amounts of HDL into endosomal recycling compartment by a pathway which is different from selective lipid uptake at the cell surface (mediated by SR-BI). Because SR-BII influence cellular cholesterol trafficking/homeostasis in a manner distinct from SR-BI, the relative expression as well as functional activities of these two isoforms create a potential means of regulating selective lipid transfer between HDL and cells.
Synonyms CD36L1; CLA-1; CLA1; HDLQTL6; SR-BI; SRB1
Note This SR-BI/SR-BII antibody is useful for Flow Cytometry (PMID: 22097902), functional studies (customer feedback), Immunocytochemistry, Western blot and Immunohistochemistry. In Western blot a band is observed at ~ 82 kDa in tissues that express SR-BI and/or SR-BII such as liver, ovary, adrenal glands, and to as lesser extent testes, heart and mammary glands.
