Protein attributes

Sequence length	569 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	Displays arylsulfatase activity at neutral pH, when co-expressed with SUMF1; arylsulfatase activity is measured in the secretion medium of retinal cell line, but no activity is recorded when measured in cell extracts.
Cofactor	Binds 1 calcium ion per subunit By similarity.
Subcellular location	Secreted. Endoplasmic reticulum. Note: Localized in the intracellular granular structures.
Tissue specificity	Expressed in placenta, in embryonic stem cells, fetal eyes and lens.
Post-translational modification	The oxidation of Cys-93 residue to 3-oxoalanine (also known as C(alpha)-formylglycine) by SUMF1/Sulfatase-modifying factor 1, seems critical for catalytic activity.
Sequence similarities	Belongs to the sulfatase family.
Caution	According to Ref.2, ARSI has no arylsulfatase activity.
