COMMENT REVIEWED REFSEQ: This record has been curated by NCBI staff. The
reference sequence was derived from DA995755.1, D90188.1 and
AC023396.4.
On Jun 15, 2006 this sequence version replaced gi:20357509.
Summary: This gene encodes the class A macrophage scavenger
receptors, which include three different types (1, 2, 3) generated
by alternative splicing of this gene. These receptors or isoforms
are macrophage-specific trimeric integral membrane glycoproteins
and have been implicated in many macrophage-associated
physiological and pathological processes including atherosclerosis,
Alzheimer's disease, and host defense. The isoforms type 1 and type
2 are functional receptors and are able to mediate the endocytosis
of modified low density lipoproteins (LDLs). The isoform type 3
does not internalize modified LDL (acetyl-LDL) despite having the
domain shown to mediate this function in the types 1 and 2
isoforms. It has an altered intracellular processing and is trapped
within the endoplasmic reticulum, making it unable to perform
endocytosis. The isoform type 3 can inhibit the function of
isoforms type 1 and type 2 when co-expressed, indicating a dominant
negative effect and suggesting a mechanism for regulation of
scavenger receptor activity in macrophages. [provided by RefSeq,
Jul 2008].
Transcript Variant: This variant (SR-AII), also known as phSR2,
uses two alternative exons and also lacks two downstream exons
compared to variant SR-AI. These differences causes an alternate 3'
end in the coding region, and has a distinct 3' UTR. It encodes
isoform type 2 that is shorter and has a different C-terminus than
isoform type 1.

publications that are available for this gene. Please see the Gene
