[5] The protein encoded by this gene is a highly hydrophobic integral membrane protein belonging to the MAL family of proteolipids.

In addition, this proteolipid is localized in compact myelin of cells in the nervous system and has been implicated in myelin biogenesis and/or function.

The protein plays a role in the formation, stabilization and maintenance of glycosphingolipid-enriched membrane microdomains.

Alternative splicing produces four transcript variants which vary from each other by the presence or absence of alternatively spliced exons 2 and 3.
