FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a member of the class A scavenger receptor family and is part of the innate antimicrobial immune system. The protein may bind both Gram-negative and Gram-positive bacteria via an extracellular, C-terminal, scavenger receptor cysteine-rich (SRCR) domain. In addition to short cytoplasmic and transmembrane domains, there is an extracellular spacer domain and a long, extracellular collagenous domain. The protein may form a trimeric molecule by the association of the collagenous domains of three identical polypeptide chains. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a null allele show altered spleen marginal zone architecture and impaired IgM responses to a pneumococcal polysaccharide vaccine. Mice homozygous for another null allele show increased susceptibility to bacterial pneumonia and enhanced inflammatory responses to inhaled particles. [provided by MGI curators]
