Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables complement component C3b binding activity; heparan sulfate proteoglycan binding activity; and heparin binding activity. Contributes to cargo receptor activity. Involved in several processes, including central nervous system development; complement-mediated synapse pruning; and endocytosis. Acts upstream of or within several processes, including activated T cell proliferation; microglia development; and neutrophil chemotaxis. Located in external side of plasma membrane and nucleus. Part of integrin alphaM-beta2 complex. Is expressed in several structures, including central nervous system; heart; hemolymphoid system; renal interstitium; and yolk sac. Human ortholog(s) of this gene implicated in lupus nephritis; persistent fetal circulation syndrome; and pre-eclampsia. Orthologous to human ITGAM (integrin subunit alpha M).
