TAS2R46 taste 2 receptor member 46 [Homo sapiens (human)] - Gene

Summary

Official Symbol: TAS2R46provided by HGNC
Official Full Name: taste 2 receptor member 46provided by HGNC
Primary source: HGNC:HGNC:18877
See related: Ensembl:ENSG00000226761 MIM:612774; AllianceGenome:HGNC:18877
Gene type: protein coding
RefSeq status: VALIDATED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: T2R46; T2R54
Summary: TAS2R46 belongs to the large TAS2R receptor family. TAS2Rs are expressed on the surface of taste receptor cells and mediate the perception of bitterness through a G protein-coupled second messenger pathway (Conte et al., 2002 [PubMed 12584440]). For further information on TAS2Rs, see MIM 604791.[supplied by OMIM, Sep 2009]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NM_001426846.1 → NP_001413775.1 taste receptor type 2 member 46 isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (2) represents an alternate 'A' allele of the SNP rs2708381, which results in a premature stop codon in T2T-CHM13 genome assembly. The resulting protein lacks one transmembrane domain, and is shorter than isoform 1.
