The function of Ensembl gene identifier ENSG00000132429 (POPDC3, popeye domain cAMP effector 3) is as follows. May play a role in the maintenance of heart function mediated, at least in part, through cAMP-binding. May play a role in the regulation of KCNK2/TREK-1-mediated current amplitude (PubMed:31610034). {ECO:0000250|UniProtKB:Q9ES81, ECO:0000269|PubMed:10882522, ECO:0000269|PubMed:31610034}.
