Human Gene LIG3 (ENST00000262327.9) from GENCODE V44
Description: Homo sapiens DNA ligase 3 (LIG3), transcript variant beta, mRNA. (from RefSeq NM_002311) RefSeq Summary (NM_002311): This gene is a member of the DNA ligase family. Each member of this family encodes a protein that catalyzes the joining of DNA ends but they each have a distinct role in DNA metabolism. The protein encoded by this gene is involved in excision repair and is located in both the mitochondria and nucleus, with translation initiation from the upstream start codon allowing for transport to the mitochondria and translation initiation from a downstream start codon allowing for transport to the nucleus. Additionally, alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]. Gencode Transcript: ENST00000262327.9 Gencode Gene: ENSG00000005156.12 Transcript (Including UTRs) Position: hg38 chr17:34,980,546-35,003,172 Size: 22,627 Total Exon Count: 20 Strand: + Coding Region Position: hg38 chr17:34,983,006-35,003,048 Size: 20,043 Coding Exon Count: 19
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
