LIG1 - DNA ligase 1 Gene

Homo sapiens

Also known as LIGI; IMD96; hLig1

Gene ID: 3978 | Gene type: protein coding

About LIG1

Cytogenetic location: 19q13.33 Genomic coordinates (GRCh38): 19:48,115,445-48,170,344 (from NCBI)

This gene has 36 transcripts (splice variants), 194 orthologues, 2 paralogues and is associated with 1 phenotype. Broad expression in bone marrow (RPKM 13.9), lymph node (RPKM 9.7) and 24 other tissues.

Summary

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]
