Functioni

PCNA-binding protein that acts as a regulator of DNA repair during DNA replication. Following DNA damage, the interaction with PCNA is disrupted, facilitating the interaction between monoubiquitinated PCNA and the translesion DNA synthesis DNA polymerase eta (POLH) at stalled replisomes, facilitating the bypass of replication-fork-blocking lesions. Also acts as a regulator of centrosome number (By similarity).By similarity

Post-translational modificationi

Monoubiquitinated at Lys-15 and Lys-24 during normal S phase, promoting its association with PCNA. Also diubiquitinated at these 2 sites. Following DNA damage, monoubiquitin chains at Lys-15 and Lys-24 are probably extended, leading to disrupt the interaction with PCNA. Polyubiquitinated by the APC/C complex at the mitotic exit, leading to its degradation by the proteasome (By similarity).By similarity

The PIP-box mediates the interaction with PCNA.By similarity
The KEN box is required for the association with the APC/C complex.By similarity
The D-box (destruction box) mediates the interaction with APC/C proteins, and acts as a recognition signal for degradation via the ubiquitin-proteasome pathway.By similarity
The initiation motif is required for efficient chain initiation by the APC/C complex E2 ligase UBE2C. It determines the rate of substrate's degradation without affecting its affinity for the APC/C, a mechanism used by the APC/C to control the timing of substrate proteolysis during the cell cycle (By similarity).By similarity
