Abstract

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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
