Ceroid-lipofuscinosis neuronal protein 6 is a protein that in humans is encoded by the CLN6gene.[4][5][6]
The CLN6 protein is part of the EGRESS complex (ER-to-Golgi relaying of enzymes of the lysosomal system), which recruits lysosomal enzymes at the endoplasmic reticulum to promote their transfer to the Golgi complex.[7] The EGRESS complex is composed of CLN6 and CLN8 proteins.[7] Loss-of-function mutations in CLN6 result in inefficient export of lysosomal enzymes from the endoplasmic reticulum and diminished levels of the enzymes at the lysosome.[7]
