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]
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 Transcription-Coupled Nucleotide Excision Repair (TC-NER) and Integrated Pancreatic Cancer Pathway. 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.
