Summary: Predicted to enable neuropeptide hormone activity. Involved in several processes, including cellular response to sodium phosphate; negative regulation of cation channel activity; and positive regulation of vascular associated smooth muscle cell apoptotic process. Located in extracellular space. Is active in neuronal dense core vesicle. Biomarker of chronic kidney disease. Orthologous to human GRP (gastrin releasing peptide).

reduction of meal size and prolongation of intermeal interval (IMI) by GRP-29 require vagal and splanchnic nerves, and the duodenum is the major conduit that communicates prolongation of IMI by GRP-29 with the brain

With increasing levels of fear, levels of gastrin-releasing peptide (Grp) are increased in medial prefrontal cortex and basolateral amygdala.

GRP-29 and GRP-27 reduced the size of the first meal, prolonged intermeal interval and increased satiety ratio, but GRP-10 failed to exhibit similar feeding responses. The data support a role for GRP-29 in the short-term regulation of food intake.

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.
