CLN6

In today's world, CLN6 has become a topic of constant conversation and general interest. Whether due to its impact on society, its relevance in the professional field or its impact on personal life, CLN6 has captured the attention of a wide spectrum of the public. Furthermore, its influence extends to multiple areas, from technology to culture, through politics and economics. As CLN6 continues to evolve and take on new dimensions, it is crucial to analyze its nature and understand its scope. This article will seek to explore different aspects of CLN6 and offer a comprehensive view of its importance today.

Ceroid-lipofuscinosis neuronal protein 6 is a protein that in humans is encoded by the CLN6 gene.^[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]
