Protein attributes

Sequence length	790 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	This protein seals, during DNA replication, DNA recombination and DNA repair, nicks in double-stranded DNA.
Catalytic activity	ATP + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + diphosphate + (deoxyribonucleotide)(n+m).
Subcellular location	NucleusBy similarity.
Sequence similarities	Belongs to the ATP-dependent DNA ligase family.
Sequence caution	The sequence AAF18258.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence AAF79833.1 differs from that shown. Reason: Erroneous gene model prediction.
