Summary: Predicted to enable neuropeptide hormone activity; type 2 galanin receptor binding activity; and type 3 galanin receptor binding activity. Involved in long-chain fatty acid import into cell and negative regulation of appetite. Predicted to be located in dense core granule. Predicted to be active in cytoplasm and extracellular space. Is expressed in esophagus and stomach fundus submucosa. Orthologous to human SPX (spexin hormone). [provided by Alliance of Genome Resources, Nov 2024]

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.
