ZG16

Chr 16

zymogen granule protein 16

Also known as: JCLN, JCLN1, ZG16A

ZG16 encodes a protein that functions in protein trafficking and may serve as a linker molecule during secretory granule formation in the trans-Golgi network, with predicted carbohydrate and peptidoglycan binding activities. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.647), but no established human genetic diseases have been definitively associated with ZG16 mutations based on the available data.
