General annotation (Comments)

Function

Involved in redox regulation of the cell. Can reduce H2O2 and short chain organic, fatty acid, and phospholipid hydroperoxides. May play a role in the regulation of phospholipid turnover as well as in protection against oxidative injury.

Catalytic activity

2 R'-SH + ROOH = R'-S-S-R' + H2O + ROH.

Donor + H2O2 = oxidized donor + 2 H2O.

Subunit structure

Homotetramer. May interact with HTR2A. Interacts with STH By similarity.

Subcellular location

Cytoplasm By similarity. Lysosome By similarity. Cytoplasmic vesicle By similarity. Note: And also found in lung secretory organelles By similarity.

Miscellaneous

The active site is the redox-active Cys-47 oxidized to Cys-SOH. Cys-SOH may rapidly react with a Cys-SH of the other subunit to form an intermolecular disulfide with a concomitant homodimer formation. The enzyme may be subsequently regenerated by reduction of the disulfide by thioredoxin By similarity.

Irreversibly inactivated by overoxidation of Cys-47 (to Cys-SO3H) upon oxidative stress By similarity.

Sequence similarities

Belongs to the ahpC/TSA family. Rehydrin subfamily.

Contains 1 thioredoxin domain.
