Protein attributes

Sequence length	260 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Reversible hydration of carbon dioxide. A major participant in the liver response to oxidative stress.
Catalytic activity	H2CO3 = CO2 + H2O.
Cofactor	Zinc.
Subcellular location	Cytoplasm.
Tissue specificity	Expressed in liver and muscle.
Induction	Repressed by 3,3',4,4',5-pentachlorobiphenyl (PenCB) and 3-methylchlantherene (3MC). Ref.2 Ref.9
Post-translational modification	S-thiolated both by thiol-disulfide exchange with glutathione disulfide and by oxyradical-initiated S-thiolation with reduced glutathione.
Miscellaneous	Expressed at much higher levels in the adipocytes of lean Zucker rats than in obese Zucker rats. Expression is higher is the adipocytes of male Zucker rats than in female Zucker rats.
Sequence similarities	Belongs to the alpha-carbonic anhydrase family.
