Overview of Gene Research
Pcna, short for Proliferating cell nuclear antigen, is an essential factor in DNA replication and repair pathways [1,3,4]. It forms a homotrimeric ring that encircles the DNA, acting as a processivity factor for DNA polymerases and a landing platform for proteins interacting with DNA and chromatin. As such, it is a key coordinator of essential cellular functions for cell growth, death, and maintenance [3,4].
In human cells, Pcna interacts with a wide variety of proteins through the PCNA-interacting protein (PIP) box, and understanding these interactions can potentially lead to the development of broad-spectrum cancer therapeutics [2]. For example, a small molecule Pcna inhibitor, AOH1996, selectively kills cancer cells by enhancing the interaction between Pcna and RPB1, dissociating Pcna from actively transcribed chromatin regions and inducing DNA double-stranded breaks in a transcription-dependent manner [5]. Also, ubiquitination of Pcna at lysine 164 is crucial for maintaining human genome stability as it promotes FANCD2-dependent mitotic DNA synthesis, preventing the accumulation of under-replicated DNA [6].
In conclusion, Pcna is vital for DNA replication and repair, and its interactions and post-translational modifications play key roles in maintaining genomic stability. The study of Pcna and its associated functions, as revealed through in vitro and in vivo studies, may offer potential therapeutic opportunities in cancer treatment [1,2,5].
