Protein of unknown function; forms a functional complex with Cvm1p; predicted canonical Asp-His-Ser catalytic triad is required for in vivo function; contains an α/β-hydrolase fold; overexpression of the Cvm1p-Cvm2p complex generates extended contacts between the vacuole and the peripheral ER; localization to the vacuolar membrane and the nucleus-vacuole junction is dependent on Cvm1p; phosphorylated; paralog of CVM1
