Summary: Predicted to enable DNA ligase (ATP) activity. Acts upstream of or within DNA replication; double-strand break repair via nonhomologous end joining; and response to hydrogen peroxide. Located in nucleus. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in inherited metabolic disorder and primary immunodeficiency disease. Orthologous to human LIG1 (DNA ligase 1).

Unchanged PCNA and DNMT1 dynamics during replication in DNA ligase I-deficient cells but abnormal chromatin levels of non-replicative histone H1.
Title: Unchanged PCNA and DNMT1 dynamics during replication in DNA ligase I-deficient cells but abnormal chromatin levels of non-replicative histone H1.
Increased presynaptic glutamate release is a key early event resulting from Lgi1-deficiency, which likely contributes to epileptogenesis.
Title: LGI1 acts presynaptically to regulate excitatory synaptic transmission during early postnatal development.
Lig1 is not absolutely required for cellular DNA replication and repair in Lig1-null cell line.
Title: DNA ligase I is not essential for mammalian cell viability.
LigI has a highly specific role in CTG repeat maintenance in the maternal germline, involved in mediating CTG expansions and in the avoidance of maternal CTG contractions.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
