  • Title: LETM1: A Single Entity With Diverse Impact on Mitochondrial Metabolism and Cellular Signaling.
    Author: Natarajan GK, Mishra J, Camara AKS, Kwok WM.
    Journal: Front Physiol; 2021; 12():637852. PubMed ID: 33815143.
    Abstract:
    Nearly 2 decades since its discovery as one of the genes responsible for the Wolf-Hirschhorn Syndrome (WHS), the primary function of the leucine-zipper EF-hand containing transmembrane 1 (LETM1) protein in the inner mitochondrial membrane (IMM) or the mechanism by which it regulates mitochondrial Ca2+ handling is unresolved. Meanwhile, LETM1 has been associated with the regulation of fundamental cellular processes, such as development, cellular respiration and metabolism, and apoptosis. This mini-review summarizes the diversity of cellular functions impacted by LETM1 and highlights the multiple roles of LETM1 in health and disease.
