Stem-loop structure preference for site-specific RNA editing by APOBEC3A and APOBEC3G

Editor rating: 7 / 10

Christopher Jolly –– Whether to not members of the APOBEC family of cytidine deaminases, which includes AID, dominate RNA or DNA or both has been a hotly debated topic since the publication of AID's role in antibody maturation in 2000. The overwhelming evidence in favour of Neuberger's DNA deamination model that emerged from 2001 onwards has produced the paradigm that APOBECs and AID perform their biological function by deaminating DNA. Nonetheless, this paper follows up earlier studies by the same authors that have demonstrated RNA-editing functions for APOBEC3A by demonstrating that substrate specificity for RNA-editing by APOBEC3A and G is dictated by RNA secondary structure, and not by the primary sequence flanking deamination sites. A bona fide RNA-editing function for APOBECs has major implications for their roles in cancer; it seems likely that mammalian cytidine deaminases will continue to surprise us for some time to come.
A Cdk1 phosphomimic mutant of MCAK impairs microtubule end recognition

Editor rating: 8 / 10

Patrizia Lavia –– The issue of how mitotic microtubules interact with the kinetochores of chromosomes is highly relevant to chromosome segregation, and hence to the generation of genetically balanced cells. Errors in the process are, on the contrary, detrimental to genetic stability. Microtubules, though being stably attached to chromosomes, must retain their dynamic ability throughout mitosis in order to move and pull the chromosomes towards the poles. MCAK is a kinesin that has an important role, is absolutely required in the process, yet its mechanism of action is known only in part. Here the authors expand our mechanistic understanding of this kinesin and propose an interesting model for its function. Their revised version is well written and has a very clear, convincing discussion that an reach a broad audience in the field of control of chromosome segregation and genome stability.
PBxplore: a tool to analyze local protein structure and deformability with Protein Blocks

Editor rating: 9 / 10

Walter de Azevedo Jr. –– The authors report the development and application of a suite of tools, called PBxplore. This computational tool can be used to analyze the dynamics and deformability of protein structures using Protein Blocks (PBs). It is an interesting development for scientists interesting in molecular dynamics simulations of protein structures.
