Previous GeneCards Identifiers 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]

LIG1 (DNA Ligase 1) is a Protein Coding gene. Diseases associated with LIG1 include Bloom Syndrome and Vaccinia. Among its related pathways are Regulation of activated PAK-2p34 by proteasome mediated degradation and Chromosome Maintenance. GO annotations related to this gene include DNA ligase activity and DNA ligase (ATP) activity. An important paralog of this gene is LIG3.
UniProtKB/Swiss-Prot for LIG1 Gene
DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair.
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.
