CC -!- FUNCTION: Reductase with a preference for aliphatic substrates. Can
CC also act on small aromatic aldehydes, steroid aldehydes and some ketone
CC substrates. {ECO:0000269|PubMed:9148949}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=an alditol + NAD(+) = an aldose + H(+) + NADH;
CC Xref=Rhea:RHEA:12785, Rhea:RHEA-COMP:9554, Rhea:RHEA-COMP:9555,

CC ChEBI:CHEBI:57783, ChEBI:CHEBI:58349; EC=1.1.1.21;
CC -!- SUBUNIT: Monomer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Detected at very low levels in urinary bladder,
CC testis and jejunum. {ECO:0000269|PubMed:9148949}.
CC -!- INDUCTION: By FGF-1 (By similarity). Up-regulated by calpain inhibitor
CC I (N-acetyl-leucyl-leucyl-norleucinal/ALLN). {ECO:0000250,
CC ECO:0000269|PubMed:9148949}.
CC -!- SIMILARITY: Belongs to the aldo/keto reductase family. {ECO:0000305}.
