Domains of unknown function (DUFs) are a large set of uncharacterized protein families that are found in the Pfam database. Here, the scale and growth of functionally uncharacterized families in biological databases are surveyed and the prospects for discovering their function are examined. In particular, the important role that structural genomics can play in identifying potential function is ...
We use the Rosetta de novo structure prediction method to produce three-dimensional structure models for all Pfam-A sequence families with average length under 150 residues and no link to any protein of known structure. To estimate the reliability of the predictions, the method was calibrated on 131 proteins of known structure. For approximately 60% of the proteins one of the top five models wa...
Recently we proposed a novel method of alignment-alignment comparison, COMPASS (the tool for COmparison of Multiple Protein Alignments with Assessment of Statistical Significance). Here we present several examples of the relations between PFAM protein families that were detected by COMPASS and that lead to the predictions of presently unresolved protein structures. We discuss relatively straigh...
background: the b-cell defect in x-linked agammaglobulinemia (xla) is caused by mutations in the gene for bruton's tyrosine kinase (btk). btk mutations result in deficient expression of btk protein in peripheral blood monocytes. methods: using the anti-btk monoclonal antibody (48-2h), a flow cytometric analysis of intra cytoplasmic btk protein expression in monocytes was performed to ident...
UNLABELLED We present TreeDom, a web tool for graphically analysing the evolutionary history of domains in multi-domain proteins. Individual domains on the same protein chain may have distinct evolutionary histories, which is important to grasp in order to understand protein function. For instance, it may be important to know whether a domain was duplicated recently or long ago, to know the ori...
BACKGROUND It has become common practice to analyse large scale sequencing data with statistical approaches based around the aggregation of rare variants within the same gene. We applied a novel approach to rare variant analysis by collapsing variants together using protein domain and family coordinates, regarded to be a more discrete definition of a biologically functional unit. METHODS Usin...
Background: The B-cell defect in X-linked agammaglobulinemia (XLA) is caused by mutations in the gene for Bruton's tyrosine kinase (BTK). BTK mutations result in deficient expression of BTK protein in peripheral blood monocytes. Methods: Using the anti-BTK monoclonal antibody (48-2H), a flow cytometric analysis of intra cytoplasmic BTK protein expression in monocytes was performed to identify I...
available on-line contains supplemental material with the sequences of the unigenes predicted from P. infestans and a comparison of the frequencies of Pfam domains in predicted proteins from P. infestans, Neurospora crassa, and Arabidopsis thaliana. e-Xtra*
In the field of occupational hygiene, researchers have been working on developing appropriate methods to estimate human exposure to pesticides in order to assess the risk and therefore to take the due decisions to improve the pesticide management process and reduce the health risks. This paper evaluates dermal exposure models to find the most appropriate. Eight models (i.e., COSHH, DERM, DREAM, ...
