Previous GeneCards Identifiers for XRN1 Gene
This gene encodes a member of the 5'-3' exonuclease family. The encoded protein may be involved in replication-dependent histone mRNA degradation, and interacts directly with the enhancer of mRNA-decapping protein 4. In addition to mRNA metabolism, a similar protein in yeast has been implicated in a variety of nuclear and cytoplasmic functions, including homologous recombination, meiosis, telomere maintenance, and microtubule assembly. Mutations in this gene are associated with osteosarcoma, suggesting that the encoded protein may also play a role in bone formation. Alternative splicing results in multiple transcript variants.

GeneCards Summary for XRN1 Gene
XRN1 (5'-3' Exoribonuclease 1) is a Protein Coding gene. Diseases associated with XRN1 include Osteogenic Sarcoma. Among its related pathways are CDK-mediated phosphorylation and removal of Cdc6 and Gene Expression. Gene Ontology (GO) annotations related to this gene include nucleic acid binding and exonuclease activity.
UniProtKB/Swiss-Prot for XRN1 Gene
Major 5-3 exoribonuclease involved in mRNA decay. Required for the 5-3-processing of the G4 tetraplex-containing DNA and RNA substrates. The kinetic of hydrolysis is faster for G4 RNA tetraplex than for G4 DNA tetraplex and monomeric RNA tetraplex. Binds to RNA and DNA (By similarity). Plays a role in replication-dependent histone mRNA degradation. May act as a tumor suppressor protein in osteogenic sarcoma (OGS).
