Protein attributes

Sequence length	332 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	May be involved in the generation of reactive oxygen species (ROS). Has low NADPH-dependent beta-naphthoquinone reductase activity, with a preference for 1,2-beta-naphthoquinone over 1,4-beta-naphthoquinone. Has low NADPH-dependent diamine reductase activity (in vitro). Ref.11
Subunit structure	Homodimer. Ref.11
Induction	Isoform 1 and isoform 2 are both activated by p53/TP53, doxorubicin, etoposide and ionizing radiation. Isoform 2 is highly activated by UV radiation. Ref.1
Sequence similarities	Belongs to the zinc-containing alcohol dehydrogenase family. Quinone oxidoreductase subfamily.
Biophysicochemical properties	Kinetic parameters: KM=215 µM for 1,2-naphthoquinone Ref.11
Sequence caution	The sequence AAC39535.1 differs from that shown. Reason: Erroneous gene model prediction.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Note: UV radiation favors the production of isoform 2.

Isoform 1 (identifier: Q53FA7-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Note: Major isoform under normal light conditions.

Isoform 2 (identifier: Q53FA7-2)

Also known as: PIG3AS;

The sequence of this isoform differs from the canonical sequence as follows:
     207-248: GAGVNLILDC...GLMGGGDING → VQANAGECFH...LPSDRNPGGP
     249-332: Missing.

Note: Major isoform under UV light exposure. Undergoes rapid proteolytic degradation by the proteasome.
