Target Background

Receptor for a number of inflammatory CC-chemokines including CCL3/MIP-1-alpha, CCL4/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. Participates in T-lymphocyte migration to the infection site by acting as a chemotactic receptor.; (Microbial infection) Acts as a coreceptor (CD4 being the primary receptor) of human immunodeficiency virus-1/HIV-1.
Gene References into Functions
  1. Conditioned media or microparticles released from obese omental adipose tissue increased CD16 and CCR5 expression on CD14(+)CD16(-) monocytes and augmented their migratory capacity towards the conditioned media from obese omental adipose tissue, itself. PMID: 27677832
  2. The block of the protein kinases phosphorylation mediated by staurosporine treatment abrogates the capture of the chemokine receptor CCR5 (CCR5) signalosome into the early endosomes. This suggests the relevant role of phosphorylation events to form steady receptor-beta-arrestin2 complexes, mediated by an ubiquitination of beta-arrestin2 and a durable phosphorylation of ERK1, which are concentrated into the early endoso...
