Funkcija

Ovaj gen kodira transmembranski protein koji se nalazi u endoplazmatskom retikulumu (ER) i reciklira između ER i Golgijevog aparata putem COPII-i COPI-obloženih vezikula.^[8] Protein CLN8 funkcionira kao receptor tereta za lizosomski topljive proteine u ER.^[8] Proteini CLN8 uparuju se sa proteinima CLN6 i formiraju EGRESS kompleks (eng. skr. ER-to-Golgi relaying of enzymes of the lysosomal system), funkcionalnu jedinicu odgovornu za eksport lizosomnih enzima iz endoplazmatskog retikuluma.^[9]

Klinički značaj

Mutacije u ovom genu povezane su sa progresivnom epilepsijom sa mentalnom retardacijom (EPMR), podtipom neuronska ceroidna lipofuscinoza (NCL). Pacijenti sa mutacijama u ovom genu imaju promijenjene nivoe sfingolipida i fosfolipida u mozgu.
