Summary: Enables amyloid-beta binding activity and complement component C3b binding activity. Contributes to cargo receptor activity. Involved in several processes, including cellular response to low-density lipoprotein particle stimulus; endocytosis; and positive regulation of leukocyte adhesion to vascular endothelial cell. Acts upstream of or within several processes, including activated T cell proliferation; integrin-mediated signaling pathway; and neutrophil chemotaxis. Located in external side of plasma membrane and membrane raft. Part of integrin alphaM-beta2 complex. Is expressed in several structures, including alimentary system; genitourinary system; heart and pericardium; hemolymphoid system; and nervous system. Used to study leukocyte adhesion deficiency 1 and psoriasis. Human ortholog(s) of this gene implicated in coronary restenosis; leukocyte adhesion deficiency; and leukocyte adhesion deficiency 1. Orthologous to human ITGB2 (integrin subunit beta 2). [provided by Alliance of Genome Resources, Nov 2024]

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.
