General annotation (Comments)

Catalytic activity

A phosphate monoester + H2O = an alcohol + phosphate. Ref.1 Ref.3

Cofactor

Binds 1 magnesium ion. Ref.3

Binds 2 zinc ions. Ref.3

Subunit structure

Homodimer. Ref.3

Subcellular location

Cell membrane; Lipid-anchorGPI-anchor Ref.1 Ref.2.

Miscellaneous

In most mammals there are four different isozymes: placental, placental-like, intestinal and tissue non-specific (liver/bone/kidney). Rat has two genes for the intestinal isozyme.

Sequence similarities
