Table 1. Categorization of CLN5 N-glycosylation sites.

N-glycosylation Residue(s)	Function	Localization(if lacking)
N179, N252, N304, N320, N330*	Folding	ER
N401	Trafficking	Golgi**
N192, N227	Lysosomal function	Lysosome

^*some N330Q protein can be observed in the lysosome.

^**N401Q mutant is temporarily accumulated in the Golgi and then secreted to the media.
