Enables S100 protein binding activity; advanced glycation end-product binding activity; and heparin binding activity. Involved in several processes, including cellular response to amyloid-beta; negative regulation of long-term synaptic potentiation; and positive regulation of cytokine production. Acts upstream of or within several processes, including induction of positive chemotaxis; negative regulation of advanced glycation end-product receptor activity; and positive regulation of macromolecule metabolic process. Located in extracellular space and plasma membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and lung. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); cardiovascular system disease (multiple); cystic fibrosis; kidney failure (multiple); and lupus nephritis. Orthologous to human AGER (advanced glycosylation end-product specific receptor). [provided by Alliance of Genome Resources, Apr 2022]
