The MUT-7 family of 3'-5' exoribonucleases is evolutionarily conserved across the animal kingdom and plays essential roles in small RNA production in the germline. Most MUT-7 homologues carry a C-terminal domain of unknown function named MUT7-C appended to the exoribonuclease domain. Our analysis shows that the MUT7-C is evolutionary ancient, as a minimal version of the domain exists as an individual protein in prokaryotes. In animals, MUT7-C has acquired an insertion that diverged during evolution, expanding its functions. Caenorhabditis elegans MUT-7 contains a specific insertion within MUT7-C, which allows binding to MUT-8 and, consequently, MUT-7 recruitment to germ granules. In addition, in C. elegans and human MUT-7, the MUT7-C domain contributes to RNA binding and is thereby crucial for ribonuclease activity. This RNA-binding function most likely represents the ancestral function of the MUT7-C domain. Overall, this study sheds light on MUT7-C and assigns two functions to this previously uncharacterized domain.

Client-server software for management, visualization, and analysis of biological microscopy images. OMERO handles images in a secure central repository where users can view, organize, analyze and share data from anywhere with internet access. Work with images from a desktop app (Windows, Mac or Linux), from the web or from 3rd party software.
View all literature mentionsA free program for multiple sequence alignment editing, visualisation and analysis that is available in two forms: a lightweight Java applet for use in web applications, and a powerful desktop application that employs web services for sequence alignment, secondary structure prediction and the retrieval of alignments, sequences, annotation and structures from public databases and any DAS 1.53 compliant sequence or annotation server. Use it to view and edit sequence alignments, analyse them with phylogenetic trees and principal components analysis (PCA) plots and explore molecular structures and annotation. Jalview has built in DNA, RNA and protein sequence and structure visualisation and analysis capabilities. It uses Jmol to view 3D structures, and VARNA to display RNA secondary structure.
View all literature mentionsSoftware for macromolecular model building, model completion and validation, and protein modelling using X-ray data. Coot displays maps and models and allows model manipulations such as idealization, rigid-body fitting, ligand search, Ramachandran plots, non-crystallographic symmetry and more. Source code is available.
View all literature mentionsA Python-based software suite for the automated determination of molecular structures using X-ray crystallography and other methods. Phenix includes programs for assessing data quality, experimental phasing, molecular replacement, model building, structure refinement, and validation. It also includes tools for reflection data and creating maps and models. Phenix can also be used for neutron crystallography. Tutorials and examples are available in the documentation tab.
