Selenoprotein K at the intersection of cellular pathways.

Selenoprotein K (selenok) is linked to the integrated stress response, which helps cells combat stressors and regain normal function. The selenoprotein contains numerous protein interaction hubs and post-translational modification sites and is involved in protein palmitoylation, vesicle trafficking, and the resolution of ER stress. Anchored to the endoplasmic reticulum (ER) membrane, selenok interacts with protein partners to influence their stability, localization, and trafficking, impacting various cellular functions such as calcium homeostasis, cellular migration, phagocytosis, gene expression, and immune response.
