HPSE heparanase

ENSG00000173083 · protein coding · Open Targets profile

Endoglycosidase that cleaves heparan sulfate proteoglycans (HSPGs) into heparan sulfate side chains and core proteoglycans. Participates in extracellular matrix (ECM) degradation and remodeling. Selectively cleaves the linkage between a glucuronic acid unit and an N-sulfo glucosamine unit carrying either a 3-O-sulfo or a 6-O-sulfo group. Can also cleave the linkage between a glucuronic acid unit and an N-sulfo glucosamine unit carrying a 2-O-sulfo group, but not linkages between a glucuronic acid unit and a 2-O-sulfated iduronic acid moiety. It is essentially inactive at neutral pH but becomes active under acidic conditions such as during tumor invasion and in inflammatory processes. Facilitates cell migration associated with metastasis, wound healing and inflammation. Enhances shedding of syndecans, and increases endothelial invasion and angiogenesis in myelomas. Acts as a procoagulant by increasing the generation of activation factor X in the presence of tissue factor and activation factor VII. Increases cell adhesion to the extracellular matrix (ECM), independent of its enzymatic activity. Induces AKT1/PKB phosphorylation via lipid rafts increasing cell mobility and invasion. Heparin increases this AKT1/PKB activation. Regulates osteogenesis. Enhances angiogenesis through up-regulation of SRC-mediated activation of VEGF. Implicated in hair follicle inner root sheath differentiation and hair homeostasis. {ECO:0000269|PubMed:12213822, ECO:0000269|PubMed:12773484, ECO:0000269|PubMed:15044433, ECO:0000269|PubMed:16452201, ECO:0000269|PubMed:18557927, ECO:0000269|PubMed:18798279, ECO:0000269|PubMed:19244131, ECO:0000269|PubMed:20097882, ECO:0000269|PubMed:20181948, ECO:0000269|PubMed:20309870, ECO:0000269|PubMed:20561914, ECO:0000269|PubMed:21131364}.

In 2 of 15 cancers, the evidence for HPSE comes mainly from inherited variants

Each row is a cancer, strongest overall evidence first. The two dots show how strong the inherited (germline) and tumour-mutation (somatic) evidence is; the line between them is the gap.

Scores run from 0 (no evidence) to 1 (strongest). A missing dot at 0 means Open Targets holds no evidence of that kind. Source: Open Targets Platform, fetched live.

gnomAD loss of function constraint: o/e 0.73676997423172 (upper bound 0.9371399879455566). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Who runs trials of these drugs

No named investigators on registry trials of HPSE's approved or late-stage drugs in the last three years.

1 trials of drugs against HPSE were stopped early

Terminated, withdrawn and suspended interventional trials of muparfostat, newest update first, live from ClinicalTrials.gov. Each reason is quoted exactly as the registry gives it; we do not sort reasons into safety, efficacy or business. Dates are the last registry update. Showing the 1 most recent of 1.

For muparfostat: what EMA and FDA publish about paediatric plans, orphan status and pediatric approvals, and how many registered studies take children. Each line is a yes, no or not published fact from the record linked under it; none of it is a forecast.

Rare pediatric disease voucher. FDA, content current as of 29 Apr 2026: “As of February 3, 2026, enactment of the Consolidated Appropriations Act, 2026, the rare pediatric disease PRV program will sunset after September 30, 2029. FDA may not award any PRVs under this program after September 30, 2029.” Voucher sale prices are not shown here; they appear only as company-reported news.
