Summaries for TOPORS Gene

Entrez Gene Summary for TOPORS Gene

  • This gene encodes a nuclear protein which is serine and arginine rich, and contains a RING-type zinc finger domain. It is highly expressed in the testis, and functions as an ubiquitin-protein E3 ligase. Mutations in this gene are associated with retinitis pigmentosa type 31. Alternatively spliced transcript variants, encoding different isoforms, have been observed for this locus. [provided by RefSeq, Sep 2010]

GeneCards Summary for TOPORS Gene

TOPORS (Topoisomerase I Binding, Arginine/Serine-Rich, E3 Ubiquitin Protein Ligase) is a Protein Coding gene. Diseases associated with TOPORS include retinitis pigmentosa 31 and topors-related retinitis pigmentosa. GO annotations related to this gene include ubiquitin-protein transferase activity and SUMO transferase activity.

UniProtKB/Swiss-Prot for TOPORS Gene

  • Functions as an E3 ubiquitin-protein ligase and as an E3 SUMO1-protein ligase. Probable tumor suppressor involved in cell growth, cell proliferation and apoptosis that regulates p53/TP53 stability through ubiquitin-dependent degradation. May regulate chromatin modification through sumoylation of several chromatin modification-associated proteins. May be involved in DNA damage-induced cell death through IKBKE sumoylation.

Post-translational modifications for TOPORS Gene

  • Phosphorylation at Ser-98 regulates the E3 ubiquitin-protein ligase activity but not the SUMO1-protein ligase activity. Phosphorylation at Ser-718 increases the E3 ubiquitin-protein ligase activity versus the SUMO1-protein ligase activity resulting in increased p53/TP53 ubiquitination and degradation.
  • Sumoylated.
  • Ubiquitination at Lys73, Lys76, Lys249, Lys760, and Lys819

TOPRS_HUMAN
  • Retinitis pigmentosa 31 (RP31) [MIM:609923]: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. {ECO:0000269 PubMed:17924349}. Note=The disease is caused by mutations affecting the gene represented in this entry.
