TAS2R43 taste 2 receptor member 43 [Homo sapiens (human)] - Gene

Summary

Official Symbol: TAS2R43provided by HGNC
Official Full Name: taste 2 receptor member 43provided by HGNC
Primary source: HGNC:HGNC:18875
See related: Ensembl:ENSG00000255374 MIM:612668; AllianceGenome:HGNC:18875
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: T2R43; T2R52
Summary: TAS2R43 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, Mar 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.
