The function of Ensembl gene identifier ENSG00000162545 (CAMK2N1, calcium/calmodulin dependent protein kinase II inhibitor 1) is as follows. Potent and specific inhibitor of CaM-kinase II (CAMK2) (By similarity). Plays a role in the maintenance of long-term retrieval- induced memory in response to contextual fear (By similarity). Modulates blood pressure and vascular reactivity via regulation of CAMK2 activity in addition to regulation of left ventricular mass (By similarity). Mediates the NLRP3 inflammasome in cardiomyocytes via acting as an inhibitor of the MAPK14/p38 and MAPK8/JNK pathways, thereby regulating ventricular remodeling and cardiac rhythm post- myocardial infarction (By similarity). Negatively effects insulin sensitivity and promotes lipid formation in adipose tissues independent of CAMK2 signaling (By similarity). {ECO:0000250|UniProtKB:Q6QWF9, ECO:0000250|UniProtKB:Q9JI15}.
