Summary
Predicted to enable 3',5'-cyclic-AMP phosphodiesterase activity and 3',5'-cyclic-GMP phosphodiesterase activity. Involved in negative regulation of insulin secretion involved in cellular response to glucose stimulus. Human ortholog(s) of this gene implicated in primary pigmented nodular adrenocortical disease 3. Orthologous to human PDE8B (phosphodiesterase 8B). [provided by Alliance of Genome Resources, Jul 2025]

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.
