| GPR1 has been described as a receptor for chemerin, although its functional relevance is currently unknown [2,23]. vMIP-I was found to be a strong inhibitor of HIV infection mediated by GPR1 [21]. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Tissue Distribution Comments | ||||||||
| Rhesus macaque brain capillary endothelial cells express GPR1 [5], as do simian astrocytes [3]. GPR1 is upregulated in normal human oral keratinocytes in cell senescence (microarray analysis) [12]. GPR1 has been identified in simian brain progenitor cells by RT-PCR [11]. In addition to the tissue distribution studies outlined above, GPR1 has also been shown to be expressed in the following cells lines: CEMss, U87, HeLa and 293T mouse cell lines using RT-PCR [4] BT-3,U87/CD4 (high); BT-20/Nm (medium); C8166 (low) human cell lines using RT-PCR [19] |

| Gene Expression and Pathophysiology Comments | |
| GPR1 serves as a coreceptor for SIV and HIV [6,8,18,26], although use of receptors other than CCR5 by HIV has been shown to be rare in vitro [27]. Only one SIV Env protein, BK28, can mediate infection via GPR1 in a CD4-dependent manner [4,14,25]. Utilisation of orphan receptors as coreceptors is variable and heterogenous [22], although one paper demonstrates GPR1's action as a coreceptor allowing replication of HIV type 1 and 2 in brain derived cell lines [19]. Inhibition of HIV-1 infection can be achieved with synthetic peptide analogues derived from the NH2 terminal extracellular region of GPR1 [10]. A small domain of a few amino acids containing a tyrosine is critical for the co-receptor activity of GPR1 [20]. |
