Protein

Extracellular sulfatase Sulf-1

Gene

SULF1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Exhibits arylsulfatase activity and highly specific endoglucosamine-6-sulfatase activity. It can remove sulfate from the C-6 position of glucosamine within specific subregions of intact heparin. Diminishes HSPG (heparan sulfate proteoglycans) sulfation, inhibits signaling by heparin-dependent growth factors, diminishes proliferation, and facilitates apoptosis in response to exogenous stimulation.

Cofactori

Ca2+By similarityNote: Binds 1 Ca2+ ion per subunit.By similarity

pH dependencei

Optimum pH is 7.0-8.0.
