Cell Type Specific Suppression of Hyper-Recombination by Human RAD18 Is Linked to Proliferating Cell Nuclear Antigen K164 Ubiquitination by Colette B. Rogers, Wendy Leung, Ryan M. Baxley, Rachel E. Kram, Liangjun Wang, Joseph P. Buytendorp, Khoi Le, David A. Largaespada, Eric A. Hendrickson, Anja-Katrin Bielinsky

“…Our analyses found that loss of RAD18 in HCT116, but neither hTERT RPE-1 nor DLD1 cell lines, resulted in elevated sister chromatid exchange, gene conversion, and gene targeting, i.e., HCT116 mutants were hyper-recombinogenic (hyper-rec). Interestingly, these phenotypes were linked to RAD18’s role in PCNA K164 ubiquitination, as HCT116 <i>PCNA^K164R/+</i> mutants were also hyper-rec, consistent with previous studies in <i>rad18</i>^−/− and <i>pcna^K164R</i> avian DT40 cells. …”

Improvement in XIa Selectivity of Snake Venom Peptide Analogue BF9-N17K Using P2′ Amino Acid Replacements by Li Ding, Zhiping Zhai, Tianxiang Qin, Yuexi Lin, Zhicheng Shuang, Fang Sun, Chenhu Qin, Hongyi Luo, Wen Zhu, Xiangdong Ye, Zongyun Chen, Xudong Luo

“…The anticoagulation assay showed that the four P2′ single-point mutants still had apparent inhibitory anticoagulation activity that selectively inhibited the human intrinsic coagulation pathway and had no influence on the extrinsic coagulation pathway or common coagulation pathway, which indicated that the single-point mutants had minimal effects on the anticoagulation activity of BF9-N17K. …”
