The protein encoded by this gene belongs to the SEC13 family of WD-repeat proteins. It is a constituent of the endoplasmic reticulum and the nuclear pore complex. It has similarity to the yeast SEC13 protein, which is required for vesicle biogenesis from endoplasmic reticulum during the transport of proteins. Multiple alternatively spliced transcript variants have been found.Synonyms: D3S1231E, Protein SEC13 homolog, SEC13-like protein 1, SEC13-related protein, SEC13L1, SEC13R
