| Schematic diagram of SULF2 with domains. | |
| Description | 870 amino acid; 100 kDa protein; post translational modification: 11 N-glycosylation sites; contains from N-term to C-term, a signal peptide (1-24), a enzymatic domain (25-400) which contains a conserved cysteine (88) essential for the catalytic activity, a hydrophilic domain (401-739) which contains four lysines and arginies rich domains suited for interactions with sulfated HSGAGs that fit the heparin-binding motif, and a glucosamine-6-sulfatase domain (740-870). |
| Expression | Widely expressed, especially in ovary, skeletal muscle, stomach, brain, uterus, heart, kidney, and placenta. |
| Localisation | Extracellular space, cell surface, plasma membrane, endoplasmic reticulum, and Golgi stack. |
| Function | SULF2 is a member of a novel family of extracellular HS 6-O endosulfatases with heparin-degrading endosulfatase activity. SULF2 desulfates HS and increases the local concentration of growth factors in the extracellular matrix. The released growth factors then bind to their cell surface receptors, with the consequent activation of cell growth and survival pathways in HCC. SULF2 up-regulated GPC3 expression and FGF2 ligand-receptor binding and signaling. It has been shown that SULF2 liberates growth factors such as Wnt3a from HSPGs such as GPC3 on the cell surface and in the extracellular matrix by desulfating heparan sulfate (HS). It has been reported that SULF2 mRNA is up-regulated in human breast cancers, and suppression of SULF2 expression decreases tumorigenesis of pancreatic cancer cell lines. SULF2 regulates PDGFRα signaling and growth in malignant glioma. |

| Entity | Hepatocellular carcinoma (HCC) |
| Prognosis | In a microarray experiment performed on paired benign and tumor tissues from HCC patients, SULF2 expression was higher in the tumors than in the benign tissues in 79 (57%) of 139 HCCs. Patients with tumors expressing high SULF2 levels had a significantly poorer prognosis than those with tumor expressing low SULF2 levels (Lai et al., 2008a). |
| Oncogenesis | Expression of SULF2 promotes HCC cell proliferation and migration. Knockdown of SULF2 decreases HCC cell proliferation and migration. SULF2 promotes tumorigenesis in nude mice and up-regulates GPC3 in vivo (Lai et al., 2008a). |
| Entity | Lung cancer |
| Prognosis | Paired samples of lung squamous carcinoma and non malignant neighboring tissue were obtained from 10 patients undergoing surgical resection. SULF2 increased in 8/10 pairs with a mean increase of 3 ± 0.3-fold. qPCR analysis of SULF2 in archived cases of lung carcinoma verified it. SULF2 increased 4 ± 0.3 fold in squamous carcinomas and 3 ± 0.4 fold in adenocarcinomas (Lemjabbar-Alaoui et al., 2010). |
| Oncogenesis | Knockdown of SULF2 or expression of dominant-negative SULF2 reduces growth of lung cancer cells. SULF2 over-expression in non-malignant bronchial epithelial cells induces a transformed phenotype in culture. SULF2 knockdown reduces growth of tumors arising from lung cancer cells (Lemjabbar-Alaoui et al., 2010). |
| Entity | Glioblastoma (GBM) |
| Prognosis | SULF2 expression is elevated in GBM. Unsing a stringent cutoff of a 10-fold increase in SULF2 SAGE tags over levels in normal brain to define high SULF2 levels, 7 of 16 GBMs has increased SULF2 expression. Strikingly, in an independent set of 424 primary human GBM tumors, SULF2 expression was increased in 46% (197/424) of tumors related to normal brain. Immunohistochemistry on an independent set of 57 primary human GBM tumors demonstrated SULF2 protein in tumor cells in 50% of tumors. SULF2 expression is associated with the proneural subtype of GBM characterized by abnormalities in the PDGFRα-signaling pathway and SULF2 expression is associated with the proneural GBM subtype (Phillips et al., 2012). |
| Oncogenesis | SULF2 confers a growth advantage to human GBM cells, SULF2 knockdown resulted in a significant decrease in cell viability. SULF2 also confers a growth advantage to human GBM cells in vivo. SULF2 confers increased tumorigenicity and proliferation. Prolonged survival confered by ablation of SULF2 in tumorigenic neurospheres. And absence of SULF2 resulted in decreased tumor cell proliferation in vivo (Phillips et al., 2012). |
