N2 - We report seven new members of the superfamily of human G protein-coupled receptors (GPCRs) found by searches in the human genome databases, termed GPR100, GPR119, GPR120, GPR135, GPR136, GPR141, and GPR142. We also report 16 orthologues of these receptors in mouse, rat, fugu (pufferfish) and zebrafish. Phylogenetic analysis shows that these are additional members of the family of rhodopsin-type GPCRs. GPR100 shows similarity with the orphan receptor SALPR. Remarkably, the other receptors do not have any close relative among other known human rhodopsin-like GPCRs. Most of these orphan receptors are highly conserved through several vertebrate species and are present in single copies. Analysis of expressed sequence tag (EST) sequences indicated individual expression patterns, such as for GPR135, which was found in a wide variety of tissues including eye, brain, cervix, stomach and testis. Several ESTs for GPR141 were found in marrow and cancer cells, while the other receptors seem to have more restricted expression patterns.
