Wolframin ER transmembrane glycoprotein (WFS1)

Wolframin ER transmembrane glycoprotein (WFS1) is a protein encoded by the WFS1 gene, residing in the membrane of the endoplasmic reticulum. It plays a vital role in cellular calcium balance, ER stress regulation, unfolded protein response, and intracellular ion homeostasis. In the pancreas, it supports insulin production and secretion; in the nervous system and sensory organs, it modulates neuronal activities, hearing, and behavioral functions. Mutations in WFS1 are implicated in Wolfram syndrome, diabetes mellitus, neurodegeneration, and sensorineural hearing loss. WFS1 interacts with proteins such as SERCA, Sigma 1 receptor, and calmodulin, further supporting its regulatory functions within the ER. Dantrolene has shown experimental promise in ameliorating ER stress in WFS1-deficient models, but no approved drugs directly target WFS1 clinically.
