Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Predicted to enable DNA ligase (ATP) activity. Involved in double-strand break repair via alternative nonhomologous end joining and mitochondrion organization. Acts upstream of or within double-strand break repair via nonhomologous end joining; mitochondrial DNA repair; and negative regulation of DNA recombination. Located in synaptonemal complex. Is expressed in several structures, including early conceptus; gonad; hemolymphoid system gland; liver; and lung. Human ortholog(s) of this gene implicated in mitochondrial DNA depletion syndrome 20 and pancreatic cancer. Orthologous to human LIG3 (DNA ligase 3). PHENOTYPE: Targeted inactivation of this gene causes embryonic growth arrest at 8.5 dpc, followed by excessive apoptosis at 9.5 dpc, and ultimately death, likely due to unrepaired DNA damage. Homozygous mutant cells display elevated sister chromatid exchange. [provided by MGI curators] |
