The conserved ubiquitin-like protein Hub1 plays a critical role in splicing in human cells
Different from canonical ubiquitin-like proteins, Hub1 does not form covalent conjugates with substrates but binds proteins non-covalently. In Saccharomyces cerevisiae, Hub1 associates with spliceosomes and mediates alternative splicing of SRC1, without affecting pre-mRNA splicing generally. Human Hub1 is highly similar to its yeast homolog, but its cellular function remains largely unexplored....
متن کاملUbiquitin-like Protein Hub1 Is Required for pre-mRNA Splicing and Localization of an Essential Splicing Factor in Fission Yeast
Hub1/Ubl5 is a member of the family of ubiquitin-like proteins (UBLs). The tertiary structure of Hub1 is similar to that of ubiquitin; however, it differs from known modifiers in that there is no conserved glycine residue near the C terminus which, in ubiquitin and UBLs, is required for covalent modification of target proteins. Instead, there is a conserved dityrosine motif proximal to the term...
متن کاملError-free Milestones in Error Prone Measurements by Dylan
A predictor variable or dose that is measured with substantial error may possess an error-free milestone, such that it is known with negligible error whether the value of the variable is to the left or right of the milestone. Such a milestone provides a basis for estimating a linear relationship between the true but unknown value of the error-free predictor and an outcome, because the milestone...

متن کاملThe extent of error-prone replication restart by homologous recombination is controlled by Exo1 and checkpoint proteins
Genetic instability, a hallmark of cancer, can occur when the replication machinery encounters a barrier. The intra-S-phase checkpoint maintains stalled replication forks in a replication-competent configuration by phosphorylating replisome components and DNA repair proteins to prevent forks from catastrophically collapsing. Here, we report a novel function of the core Schizosaccharomyces pombe...
