Protein CLN8is aproteinthat in humans is encoded by theCLN8gene.[5][6]

Molecular biology

[edit]

This gene encodes a transmembrane protein that localizes to theendoplasmic reticulum(ER) and recycles between the ER and theGolgi apparatusviaCOPII- andCOPI-coated vesicles.[7]CLN8 protein functions as a cargo receptor for lysosomal soluble proteins in the ER.[7]CLN8 proteins pair withCLN6proteins to form theEGRESS complex(ER-to-Golgirelaying ofenzymes of the lysosomalsystem), the functional unit responsible for the export of lysosomal enzymes from theendoplasmic reticulum.[8]

Clinical

[edit]

Mutations in this gene are associated withprogressive epilepsy with mental retardation(EPMR), a subtype ofneuronal ceroid lipofuscinosis(NCL). Patients with mutations in this gene have altered levels ofsphingolipidandphospholipidsin thebrain.
