The sterol-sensing endoplasmic reticulum (ER) membrane protein TRC8 hampers ER to Golgi transport of sterol regulatory element-binding protein-2 (SREBP-2)/SREBP cleavage-activated protein and reduces SREBP-2 cleavage

Pheomelanin Yellow/red pigment Weak UV absorption Generates free radicals when UV-exposed Dominant in pale, red-haired, or Northern-European skin types Strongly linked to high skin cancer risk Research confirms this dichotomy: eumelanin is UV-absorbent and protective, while pheomelanin acts as a photosensitizer that can amplify UV damage
