Other 7TM proteins C

Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).

Overview

Show »« Hide

These proteins are predicted to have 7TM domains, but functional studies have yet to confirm them as G protein-coupled receptors.

MOA1 | ocular albinism 1 (Nettleship-Falls) | NYS6 | Ocular albinism type 1 protein

Genes

GPR143 (Hs), Gpr143 (Mm), Gpr143 (Rn)

Ensembl ID

ENSG00000101850 (Hs), ENSMUSG00000025333 (Mm), ENSRNOG00000003543 (Rn)

UniProtKB AC

GPR157 C Show summary »« Hide summary More detailed page go icon to follow link

Target Id	205
Nomenclature	GPR157
Genes	GPR157 (Hs), Gpr157 (Mm), Gpr157 (Rn)
Ensembl ID	ENSG00000180758 (Hs), ENSMUSG00000047875 (Mm), ENSRNOG00000017528 (Rn)
UniProtKB AC	Q5UAW9 (Hs), Q8C206 (Mm), Q5FVG1 (Rn)
Principal transduction	-
Comment	GPR157 has ambiguous sequence similarities to several different GPCR families (class A, class B and the slime mould cyclic AMP receptor). Because of its distant relationship to other GPCRs, it cannot be readily classified.
