Summaries for LIG1 Gene

Entrez Gene Summary for LIG1 Gene

  • This gene encodes a member of the ATP-dependent DNA ligase protein family. The encoded protein functions in DNA replication, recombination, and the base excision repair process. Mutations in this gene that lead to DNA ligase I deficiency result in immunodeficiency and increased sensitivity to DNA-damaging agents. Disruption of this gene may also be associated with a variety of cancers. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

GeneCards Summary for LIG1 Gene

LIG1 (DNA Ligase 1) is a Protein Coding gene. Diseases associated with LIG1 include Bloom Syndrome and Vaccinia. Among its related pathways are DNA strand elongation and Chromosome Maintenance. GO annotations related to this gene include DNA ligase activity and DNA ligase (ATP) activity.

UniProtKB/Swiss-Prot for LIG1 Gene

  • DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair.

Tocris Summary for LIG1 Gene

  • Ligases are enzymes which catalyze the joining of two molecules with concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. They belong to the E.C. 6 class of enzymes, which also includes synthases and carboxylases.
