COPB1
COPB1 encodes coatomer protein complex subunit beta 1, a core component of the COPI coat that mediates retrograde vesicle transport from the Golgi to the endoplasmic reticulum and supports Golgi structure and lipid-droplet trafficking. A locus near COPB1 has emerged in genome-wide gene-by-environment analyses as interacting with UVB exposure to affect circulating vitamin D status, consistent with its use here as sun-response context for vitamin D genetics.
