Protein Structure

UniProt Annotation

Function

Catalyzes the NADPH-dependent reduction of several pentoses, tetroses, trioses, alpha-dicarbonyl compounds and L- xylulose. Participates in the uronate cycle of glucose metabolism. May play a role in the water absorption and cellular osmoregulation in the proximal renal tubules by producing xylitol, an osmolyte, thereby preventing osmolytic stress from occurring in the renal tubules.

Subcellular Localization

Membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}. Apical cell membrane {ECO:0000269PubMed:11882650}; Peripheral membrane protein {ECO:0000269PubMed:11882650}. Note=Probably recruited to membranes via an interaction with phosphatidylinositol (By similarity). In kidney, it is localized in the brush border membranes of proximal tubular cells. {ECO:0000250}.

Disease Associations

Tissue Specificity

Highly expressed in kidney, liver and epididymis. Expressed at intermediate level in lung. Weakly or not expressed in brain, heart, spleen and testis. {ECO:0000269PubMed:11882650}.
