CCR1, the role of which, according to studies, is to protect humans from inflammatory response, and susceptibility to virus and parasite, encodes a member of the beta chemokine receptor family (found on the surface of certain cells that interact with a type of cytokine called a chemokine).
Knockout studies of the mouse homolog suggested the roles of this gene in host protection from inflammatory response, and susceptibility to virus and parasite. This gene encodes a member of the beta chemokine receptor family, which belongs to G protein-coupled receptors. Chemokine receptors are cytokine receptors found on the surface of certain cells that interact with a type of cytokine called a chemokine.
