Recombinant human LETM1 (Leucine zipper-EF-hand containing transmembrane protein 1) is a mitochondrial protein encoded by the *LETM1* gene located on chromosome 17q21.31. Initially identified as a candidate gene in Wolf-Hirschhorn syndrome (WHS), LETM1 is implicated in mitochondrial ion homeostasis, particularly in regulating calcium and potassium transport across the mitochondrial inner membrane. It plays a critical role in maintaining mitochondrial structure, energy metabolism, and apoptosis. LETM1 contains conserved EF-hand and leucine zipper domains, suggesting its involvement in protein-protein interactions and calcium signaling. Dysregulation of LETM1 has been linked to neurodegenerative diseases, cancer, and metabolic disorders, highlighting its broad physiological relevance.
Recombinant LETM1 protein, typically produced in *E. coli* or mammalian expression systems, is widely used to study its molecular mechanisms, interactions, and structural properties. Its applications include *in vitro* functional assays, antibody production, and disease modeling. Recent studies suggest LETM1 may act as a Ca²⁺/H⁺ antiporter, influencing mitochondrial bioenergetics and reactive oxygen species (ROS) regulation. Ongoing research aims to clarify its role in mitochondrial dynamics and its potential as a therapeutic target for disorders linked to mitochondrial dysfunction.
