Summary: Enables somatostatin receptor activity. Involved in several processes, including brain development; cellular response to estradiol stimulus; and spermatogenesis. Predicted to be located in cytoplasm and membrane. Predicted to be part of G protein-coupled receptor heterodimeric complex and G protein-coupled receptor homodimeric complex. Predicted to be active in neuron projection and plasma membrane. Orthologous to human SSTR1 (somatostatin receptor 1). [provided by Alliance of Genome Resources, Dec 2024]

In the jejunums of Cryptosporidium-parvum-infected rats, daily octreotide therapy decreased mRNA levels of SSTR1 on day 14 post-infection, although it increased mRNA levels of SSTR1 on day 50 post-infection. Specific SSTRs may regulate the inflammatory pathway in the rat intestinal inflammation model.

All SSTR1-5 proteins were observed at embryonal day 10 and increased with time in major structures, but the localization varied between the different subtypes. Only SSTR1 protein co-localized to a higher extent with the islet hormones studied.

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.
