Summary
This gene encodes four products of the tachykinin peptide hormone family, substance P and neurokinin A, as well as the related peptides, neuropeptide K and neuropeptide gamma. These hormones are thought to function as neurotransmitters which interact with nerve receptors and smooth muscle cells. They are known to induce behavioral responses and function as vasodilators and secretagogues. Substance P is an antimicrobial peptide with antibacterial and antifungal properties. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2014]

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.

    Status: REVIEWED

    Description
    Transcript Variant: Transcript variant beta encodes the full-length form of this gene. It encodes hormones substance P, neurokinin A, as well as the neuropeptide K.

    Status: REVIEWED

    Description
    Transcript Variant: As compared to the full-length transcript variant beta, variant alpha lacks exon 6, and therefore does not encode neuropeptide K, neurokinin A, or neuropeptide gamma. This transcript does encode the hormone substance P located on exon 3.

    Status: REVIEWED

    Description
    Transcript Variant: As compared to the full-length transcript variant beta, variant gamma lacks exon 4, and therefore does not encode neuropeptide K. This transcript does encode substance P, neurokinin A, and is the only variant that encodes neuropeptide gamma.

    Status: REVIEWED

    Description
    Transcript Variant: As compared to the full-length transcript variant beta, variant delta lacks both exons 4 and 6; therefore, it does not encode neurokinin A, neuropeptide K, or neuropeptide gamma. It does encode the hormone substance P located on exon 3.
