Arabidopsis PCNA1 and PCNA2 differ in their efficiency for ubiquitination and sumoylation, leading to their differential responses to DNA damage in yeast cells.
Title: Similarities and differences between Arabidopsis PCNA1 and PCNA2 in complementing the yeast DNA damage tolerance defect.

PCNA1 and PCNA2 may cooperate in planta by forming homo- and heterotrimeric rings.
Title: Arabidopsis thaliana: proliferating cell nuclear antigen 1 and 2 possibly form homo- and hetero-trimeric complexes in the plant cell.

Ubiquitin-conjugating enzymes and RAD5a proteins are involved in the ubiquitination of plant PCNA at lysine 164.
Title: RAD5a ubiquitin ligase is involved in ubiquitination of Arabidopsis thaliana proliferating cell nuclear antigen.

These results clearly show that plant PCNA is post-translationally modified in bacteria and may be sumoylated in a plant cell at various sites.
Title: Arabidopsis thaliana proliferating cell nuclear antigen has several potential sumoylation sites.

atomic resolution crystal structures of the PCNA1 and PCNA2 complexed with the C-terminal segment of human p21; structures demonstrated that PCNA1 & 2 adopt identical architectures
Title: Crystal structures of the Arabidopsis thaliana proliferating cell nuclear antigen 1 and 2 proteins complexed with the human p21 C-terminal segment.
