Protein

C-C chemokine receptor type 5

Gene

CCR5

Organism
Callithrix humeralifera (Tassel-eared marmoset)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein inferred from homologyi

Functioni

Receptor for a number of inflammatory CC-chemokines including MIP-1-alpha, MIP-1-beta and RANTES and subsequently transduces a signal by increasing the intracellular calcium ion level. May play a role in the control of granulocytic lineage proliferation or differentiation (By similarity).By similarity

Post-translational modificationi

Sulfated on at least 2 of the N-terminal tyrosines. Sulfation is required for efficient binding of the chemokines, CCL3 and CCL4 (By similarity).By similarity
O-glycosylated, but not N-glycosylated. Ser-6 appears to be the major site. Also sialylated glycans present which contribute to chemokine binding. Ser-17 may also be glycosylated and, if so, with small moieties such as a T-antigen (By similarity).By similarity
Palmitoylation in the C-terminal is important for cell surface expression.By similarity
Phosphorylation on serine residues in the C-terminal is stimulated by binding CC chemokines especially by APO-RANTES.By similarity

Interactioni

Subunit structurei

Interacts with PRAF2. Efficient ligand binding to CCL3/MIP-1alpha and CCL4/MIP-1beta requires sulfation, O-glycosylation and sialic acid modifications. Glycosylation on Ser-6 is required for efficient binding of CCL4. Interacts with GRK2. Interacts with ARRB1 and ARRB2. Interacts with CNIH4.By similarity
