Summary: Enables phenylethanolamine N-methyltransferase activity. Predicted to be involved in epinephrine biosynthetic process and norepinephrine metabolic process. Predicted to be located in axon; dendrite; and perikaryon. Predicted to be active in cytosol. Is expressed in several structures, including adrenal gland; brain; gonad; and metanephros. Human ortholog(s) of this gene implicated in Alzheimer's disease; hypertension; and multiple sclerosis. Orthologous to human PNMT (phenylethanolamine N-methyltransferase).

Data suggest that Pnmt plays role in fear response and startle reactivity; compared with wild-type mice, Pnmt-knockout mice exhibit reduced contextual fear but normal cued fear.

Although temperature was normal in Pnmt(-/-) mice, the brown fat response to cold was abnormal with no increase in Ucp-1 or Pgc-1alpha mRNA levels (but with an exaggerated cold-induced lipid loss from the tissue).
Title: Effect of epinephrine deficiency on cold tolerance and on brown adipose tissue.
Neuronal nitric oxide synthase gene inactivation reduces the expression of vasopressin in the hypothalamic paraventricular nucleus and of PNMT in the adrenal gland of the mouse.

Epinephrine is required for normal blood pressure and cardiac filling responses to stress but is not required for tachycardia during stress or normal cardiovascular function at rest in the knockout mouse.

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.
