Possesses ATPase activity (By similarity). Plays a part in calcium-regulated keratinocyte activation in epidermal repair mechanisms. Has no effect on cell proliferation. Negatively regulates mitochondrial fusion in cooperation with mitofusin proteins (MFN1-2). The majority is localized in the cytoplasm and a small amount is associated with mitochondria. Expressed in brain. Also expressed in glioblastoma cells. Increased expression in glioblastomas and on wounding, in basal keratinocytes. This expression is calcium ion-dependent. Belongs to the zinc-containing alcohol dehydrogenase family. Quinone oxidoreductase subfamily. Truncated N-terminus.
