Protein attributes

Sequence length	432 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Catalytic activity	A phosphate monoester + H2O = an alcohol + phosphate.
Subcellular location	Lysosome membrane; Single-pass membrane protein; Lumenal side By similarity. Lysosome lumen By similarity. Note: The soluble form arises by proteolytic processing of the membrane-bound form By similarity.
Post-translational modification	The membrane-bound form is converted to the soluble form by sequential proteolytic processing. First, the C-terminal cytoplasmic tail is removed. Cleavage by a lysosomal protease releases the soluble form in the lysosome lumen By similarity.
Sequence similarities	Belongs to the histidine acid phosphatase family.
