G Protein Coupled Receptor 162 (GPR162)

GPR162 was identified upon genomic analysis of a gene-dense region at human chromosome 12p13. It appears to be mainly expressed in the brain; however, its function is not known. Alternatively spliced transcript variants encoding different isoforms have been identified.BLAST searches and phylogenetic analyses showed that only four of the receptors are closely related to previously characterised GPCRs, GPR150 and GPR154 to oxytocin/vasopressin receptors, GPR162 and GPR139 are remarkably well conserved while GPR148 seems to be evolving rapidly. Analyses using expressed sequence tags (ESTs) indicate that all the new receptors except GPR153 have the CNS as a major site of expression.
