Protein attributes

Sequence length	137 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

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 structure	Heterodimer with UBC13.
Miscellaneous	Present with 2760 molecules/cell in log phase SD medium. Ref.6
Sequence similarities	Belongs to the ubiquitin-conjugating enzyme family.
