Centrioles organise centrosomes and template cilia and flagella. Several centriole and centrosome proteins have been linked to microcephaly (MCPH), a neuro-developmental disease associated with small brain size. CPAP (MCPH6) and STIL (MCPH7) are required for centriole assembly, but it is unclear how mutations in them lead to microcephaly. We show that the TCP domain of CPAP constitutes a novel proline recognition domain that forms a 1:1 complex with a short, highly conserved target motif in STIL. Crystal structures of this complex reveal an unusual, all-β structure adopted by the TCP domain and explain how a microcephaly mutation in CPAP compromises complex formation. Through point mutations, we demonstrate that complex formation is essential for centriole duplication in vivo. Our studies provide the first structural insight into how the malfunction of centriole proteins results in human disease and also reveal that the CPAP-STIL interaction constitutes a conserved key step in centriole biogenesis.

A software application for such tasks as photo retouching, image composition and image authoring. It has many capabilities such as it can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc. GIMP is expandable and extensible and designed to be augmented with plug-ins and extensions. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted.

View all literature mentionsCancer Research UK is the world''s leading charity dedicated to beating cancer through research. We''ve saved millions of lives with our groundbreaking work into preventing, diagnosing and treating cancer. People''s chances of surviving cancer have doubled in the last 40 years, and we''ve been at the heart of that progress. But more than one in three of us will still get cancer at some point. Our vital work, funded entirely by the public, will help ensure that millions more people survive. Our aim is to save lives from cancer. More people are beating cancer than ever before thanks to our work and your support. We work in the areas where we can make the most impact: * Research we support the work of over 4,000 scientists, doctors and nurses across the UK to investigate all aspects of cancer. * Information we work to prevent cancer and help people cope with its effects by providing information for cancer patients and their families, health professionals and the general public. * Influencing public policy we campaign to keep cancer at the top of the health agenda. Cancer Research UK is a registered charity in England and Wales (1089464) and in Scotland (SC041666). Registered as a company limited by guarantee in England & Wales No. 4325234.
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 molecular refinement program with two main modes: REVIEW, which checks and updates the input model to establish that the geometric restraints can be properly set up, and REFINE mode, which is the standard mode and documented in keywords. In REVIEW users can: check model coordinates and write an extended output set of coordinates, find disulphide bonds and other covalent links, cis-peptides, output the sequence and REMARK records. In REFINEMENT mode users can carry out rigid body, tls, restrained or unrestrained refinement against Xray data, or idealisation of a macromolecular structure. Also in REFINEMENT mode, Refmac produces an MTZ output file containing weighted coefficients for SigmaA weighted mFo-DFcalc and 2mFo-DFcalc maps. The program is supported by CCP4.
