Mms2p (Saccharomyces cerevisiae) is product of expression of MMS2 gene.

FUNCTION: Has a role in the DNA error-free postreplication repair (PRR) pathway. Lacks catalytic activity by itself. The UBC13/MMS2 heterodimer catalyzes the synthesis of non-canonical poly- ubiquitin chains that are linked through 'Lys-63'.

SUBUNIT: Heterodimer with UBC13.

INTERACTION: P53751:-; NbExp=1; IntAct=EBI-11035, EBI-28557; P40210:SIP5; NbExp=1; IntAct=EBI-11035, EBI-27280; P52490:UBC13; NbExp=2; IntAct=EBI-11035, EBI-19777;

MISCELLANEOUS: Present with 2760 molecules/cell in log phase SD medium.

SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family.

NCBI GenPept GI number(s): 6321351
Species: Saccharomyces cerevisiae
