Protein FULL name:

DNA ligase

Protein SHORT name:


Cdc9p (Saccharomyces cerevisiae) is product of expression of CDC9 gene.

Cdc9p is involved in:

BER in Saccharomyces cerevisiae MMR in Saccharomyces cerevisiae NER in Saccharomyces cerevisiae


FUNCTION: DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair. The mitochondrial form is required for mitochondrial DNA maintenance but is non-essential while the nuclear form is essential for cell viability.

CATALYTIC ACTIVITY: ATP + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + diphosphate + (deoxyribonucleotide)(n+m).

COFACTOR: Magnesium (By similarity).

INTERACTION: P15891:ABP1; NbExp=1; IntAct=EBI-5991, EBI-2036; P20449:DBP5; NbExp=1; IntAct=EBI-1009737, EBI-5617; P36156:ECM4; NbExp=1; IntAct=EBI-1009737, EBI-2042717;

SUBCELLULAR LOCATION: Nucleus. Mitochondrion.

MISCELLANEOUS: Cdc9 is included within the category of so-called 'start genes', encoding proteins which are required in early G1, when the cell is faced with the option of initiating a further cell cycle.

MISCELLANEOUS: Present with 149 molecules/cell in log phase SD medium.

SIMILARITY: Belongs to the ATP-dependent DNA ligase family.

NCBI GenPept GI number(s): 6320038
Species: Saccharomyces cerevisiae
