Crystal Structure of Human PRPF4B kinase domain in complex with 4-{5-[(2-Chloro-pyridin-4-ylmethyl)-carbamoyl]-thiophen-2-yl}-benzo[b]thiophene-2-carboxylic acid amineCrystal Structure of Human PRPF4B kinase domain in complex with 4-{5-[(2-Chloro-pyridin-4-ylmethyl)-carbamoyl]-thiophen-2-yl}-benzo[b]thiophene-2-carboxylic acid amine

FunctionPRP4B_HUMAN Has a role in pre-mRNA splicing. Phosphorylates SF2/ASF. Publication Abstract from PubMedPRP4 kinase is known for its roles in regulating pre-mRNA splicing and beyond. Therefore, a wider spectrum of PRP4 kinase substrates could be expected. The role of PRP4 kinase in cancer is also yet to be fully elucidated. Attaining specific and potent PRP4 inhibitors would greatly facilitate the study of PRP4 biological function and its validation as a credible cancer target. In this report, we verified the requirement of enzymatic activity of PRP4 in regulating cancer cell growth and identified an array of potential novel substrates through orthogonal proteomics approaches. The ensuing effort in structural biology unveiled for the first time unique features of PRP4 kinase domain and its potential mode of interaction with a low molecular weight inhibitor. These results provide new and important information for further exploration of PRP4 kinase function in cancer.
