EFICAz (Enzyme Function Inference by Combined Approach) is an automatic engine for large-scale enzyme function inference that combines predictions from four different methods developed and optimized to achieve high prediction accuracy: (i) recognition of functionally discriminating residues (FDRs) in enzyme families obtained by a Conservation-controlled HMM Iterative procedure for Enzyme Family...
SBASE is a database of annotated protein domain sequences representing various structural, functional, ligand binding and topogenic segments of proteins. The current release of SBASE contains 27,211 entries which are provided with standardized names in order to facilitate retrieval. SBASE is cross-referenced to the major protein and nucleic acid databanks as well as to the PROSITE catalog of pr...
Here we report the complete genome sequence of Singapore grouper iridovirus (SGIV). Sequencing of the random shotgun and restriction endonuclease genomic libraries showed that the entire SGIV genome consists of 140,131 nucleotide bp. One hundred sixty-two open reading frames (ORFs) from the sense and antisense DNA strands, coding for lengths varying from 41 to 1,268 amino acids, were identified...
The calcium-activated neutral proteases, mu- and m-calpain, along with their inhibitor, calpastatin, have been demonstrated to mediate a variety of Ca(2+)-dependent processes including signal transduction, cell proliferation, cell cycle progression, differentiation, apoptosis, membrane fusion, platelet activation and skeletal muscle protein degradation. The cDNA coding for yak calpastatin was a...
The accelerated growth of the molecular sequencing data has generated a pressing need for advanced sequence annotation tools. This paper reports a new method, termed MOTIFIND (Motif Identification Neural Design), for rapid and sensitive protein family identification. The method is extended from our previous gene classification artificial neural system and employs two new designs to enhance the ...
InterPro, an integrated documentation resource of protein families, domains and functional sites, was created to integrate the major protein signature databases. Currently, it includes PROSITE, Pfam, PRINTS, ProDom, SMART, TIGRFAMs, PIRSF and SUPERFAMILY. Signatures are manually integrated into InterPro entries that are curated to provide biological and functional information. Annotation is pro...
Human GNL3 (nucleostemin) is a recently discovered nucleolar protein with pivotal functions in maintaining genomic integrity and determining cell fates of various normal and cancerous stem cells. Recent reports suggest that targeting this GTP-binding protein may have therapeutic value in cancer. Although, sequence analyzing revealed that nucleostemin (NS) comprises 5 permuted GTP-binding motifs...
Computational methods such as sequence alignment and motif construction are useful in grouping related proteins into families, as well as helping to annotate new proteins of unknown function. These methods identify conserved amino acids in protein sequences, but cannot determine the specific functional or structural roles of conserved amino acids without additional study. In this work, we prese...
The Chromosome-centric Human Proteome Project (C-HPP) is aimed to identify the variety of protein products and transcripts of the number of chromosomes. The Russian part of C-HPP is devoted to the study of the human chromosome 18. Using widely accepted Tophat and SpliceGrapher, a tool for accurate splice sites and alternative mRNA isoforms prediction, we performed the extensive mining of the sp...
Predicting calcium binding proteins and identifying calcium-binding sites is an important problem in the field of proteomics. Most of the currently used methods employ structural protein data to predict calcium-binding sites. Here we present a method developed to predict calcium-binding proteins and identify calcium-binding sites from protein sequence data using machine learning techniques such...
