Neuronatin Protein in Health and Disease

Abstract

Neuronatin (NNAT) was first identified as a brain-specific gene crucial for brain development. Over the years, NNAT has been studied in different developing and post-developed tissues and organs. While NNAT manifests functional and structural similarities to the phospholamban gene, its physiological and pathological roles in healthy and diseased tissues have not been precisely identified. Ca²⁺ signaling, glucose transport, insulin secretion, and inflammation modulated at different pathological conditions have been proposed to be governed by NNAT. This review describes the current findings of cellular molecular pathways known to be modified concomitantly with an alteration in NNAT expression, and it highlights the need to conduct extensive investigation regarding the role of NNAT in health and disease.
