Summary: Predicted to enable ceramide binding activity. Acts upstream of or within several processes, including adult walking behavior; glutamate reuptake; and neurofilament cytoskeleton organization. Located in endoplasmic reticulum. Is expressed in several structures, including adrenal gland; gonad; hemolymphoid system gland; nervous system; and retina. Used to study neuronal ceroid lipofuscinosis 8. Human ortholog(s) of this gene implicated in neuronal ceroid lipofuscinosis 8 and neuronal ceroid lipofuscinosis 8 northern epilepsy variant. Orthologous to human CLN8 (CLN8 transmembrane ER and ERGIC protein). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
