Summary: Enables tachykinin receptor activity. Involved in several processes, including positive regulation of uterine smooth muscle contraction; regulation of dopamine metabolic process; and response to estradiol. Located in dendrite membrane and neuronal cell body membrane. Used to study hypertension. Biomarker of visual epilepsy.

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.
