Could regulate export of the bud site and axial growth sites selection protein AXL2 and possibly other secretory proteins from the endoplasmic reticulum in COPII-coated vesicles. Seems to be required for axial budding pattern in haploid cells. Resides in the endoplasmic and Golgi compartments, and then packaged into endoplasmic reticulum derived vesicles. Defects in cell polarity. Strains homozygous for ERV14 deletion do not sporulate. Present with 7110 molecules/cell in log phase SD medium. Belongs to the cornichon family.
