Sequence of human villin: a large duplicated domain homologous with other actin-severing proteins and a unique small carboxy-terminal domain related to villin specificity
Villin is a calcium-regulated actin-binding protein that caps, severs, and bundles actin filaments in vitro. This 92,500-D protein is a major constituent of the actin bundles within the microvilli of the brush border surface of intestinal and kidney proximal tubule cells. Villin is a very early marker of cells involved in absorption and its expression is highly increased during intestinal cell ...
متن کاملIn vivo analysis of functional domains from villin and gelsolin
Transfected CV1 cells were used to compare the in vivo effects of various domains of villin and gelsolin. These two homologous actin modulating proteins both contain a duplicated severin-like sequence. Villin has in addition a carboxy-terminal domain, the headpiece, which accounts for its bundling activity. The effects of the villin-deleted mutants were compared with those of native villin. Our...
متن کاملHomologous sequences in cholera toxin A and B subunits to peptide domains in myelin basic protein.
Recent reports that myelin basic protein (MBP) can be ADP-ribosylated and contains specific sites that bind GTP and GM1 ganglioside, have suggested an analogy to the properties of cholera toxin. Comparisons of pairs of sequences between these two proteins yielded two regions of homology between MBP and the cholera toxin B (chol B) subunit, and one region of homology with the cholera toxin A (ch...
متن کاملAutomated clustering of homologous domains
The ProDom database is a comprehensive set of protein domain families automatically generated from the SWISS-PROT and TrEMBL sequence databases. An associated database, ProDom-CG, has been derived as a restriction of ProDom to completely sequenced genomes. The ProDom construction method is based on iterative PSI-BLAST searches and multiple alignments are generated for each domain family. The Pr...
متن کاملFeatureMap3D—a tool to map protein features and sequence conservation onto homologous structures in the PDB
FeatureMap3D is a web-based tool that maps protein features onto 3D structures. The user provides sequences annotated with any feature of interest, such as post-translational modifications, protease cleavage sites or exonic structure and FeatureMap3D will then search the Protein Data Bank (PDB) for structures of homologous proteins. The results are displayed both as an annotated sequence alignm...
