Cholecystokinin (CCK)-A and CCK-B receptors are highly homologous members of the seven transmembrane domain G-protein-coupled receptor super-family. Peptides in the cholecystokinin (CCK) family have a variety of biological functions in the central

Cholecystokinins (CCK) are derived from preprocholecystokinin. They are widely expressed in gastrointestinal tissues and in the CNS.

C-C chemokine receptor type 1 (CCR1) is a G protein-coupled receptor member of the CC chemokine subfamily of receptors. Following interaction with its specific chemokine ligands, like macrophage inflammatory protein 1 alpha (MIP-1 alpha), regulated

C-C chemokine receptor type 5 (CCR5) is a G protein-coupled receptor and a co-receptor for the entry of human immunodeficiency virus-1 (HIV-1) into cells. CCR5 chemokine receptor is involved in leucocytes chemotaxis to sites of inflammation and

Cluster of Differentiation 112 (CD112), also known as poliovirus receptor related protein 2 (PVRL2 or PRR2), is a single-pass type I transmembrane glycoprotein belonging to the Immunoglobulin superfamily. CD112 protein also serves as an entry for

CD155, commonly known as PVR (poliovirus receptor) and Necl-5 (nectin-like molecule-5), is a type I transmembrane single-span glycoprotein, and belongs to the nectins and nectin-like (Necl) subfamily. CD155 was originally identified based on its

CD16 is a cluster of differentiation molecule found on the surface of natural killer (NK) cells, monocytes and macrophages. It can be used to isolate populations of NK cells by antibodies directed towards CD16, using fluorescent-activated cell

CD16 is a cluster of differentiation molecule found on the surface of natural killer cells, monocytes and macrophages. It can be used to isolate populations of these cells by antibodies directed towards CD16, using fluorescent-activated cell sorting

CD16 has been identified as Fc receptors Fc?RIIIa (CD16a) and Fc?RIIIb (CD16b). These receptors bind to the Fc portion of IgG antibodies which then activates the NK cell for antibody-dependent cell-mediated cytotoxicity.

Cell surface glycoprotein CD200 receptor 1 is a protein that in humans is encoded by the CD200R1 gene. This gene encodes a receptor for the OX-2 membrane glycoprotein.

FCGR2B (CD32B) is a low affinity receptor for Immunoglobulin G (IgG). Mutations in the gene in humans lead to a lupus phenotype.

Human studies suggest expression of CD32C could help predict patient responses to vaccines. CD32C normally contains a termination codon, but 7%–15% of individuals carry a mutation that changes it into a full-length open reading frame.
