May play a role in the regulation of cytokinesis (PubMed:21857149, PubMed:25666058). May play a role in signaling by stimulating protein glycosylation. Induces neuritogenesis by activating the Ras-MAP kinase pathway and is necessary for the survival of cerebellar neurons (By similarity). Does not appear to play a major role in ciliogenesis (By similarity). {ECO:0000250|UniProtKB:P28658, ECO:0000250|UniProtKB:Q9ER24, ECO:0000269|PubMed:21857149, ECO:0000269|PubMed:25666058}. This is the function of ATXN10 (ataxin 10, ENSG00000130638).
