160-409: Is an algorithm used for calculating sequence similarity between biological sequences, such as nucleotide sequences of DNA and amino acid sequences of proteins. BLAST is a powerful tool for finding sequences similar to the query sequence within the same organism or in different organisms. It searches the query sequence on NCBI databases and servers and posts the results back to the person's browser in
180-685: Is part of the (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States . The NCBI is located in Bethesda, Maryland , and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper . The NCBI houses a series of databases relevant to biotechnology and biomedicine and is an important resource for bioinformatics tools and services. Major databases include GenBank for DNA sequences and PubMed ,
200-825: The European Molecular Biology Laboratory (EMBL) and the DNA Data Bank of Japan (DDBJ). Since 1992, NCBI has grown to provide other databases in addition to GenBank. NCBI provides the Gene database, Online Mendelian Inheritance in Man , the Molecular Modeling Database (3D protein structures), dbSNP (a database of single-nucleotide polymorphisms ), the Reference Sequence Collection, a map of
220-588: The human genome , and a taxonomy browser, and coordinates with the National Cancer Institute to provide the Cancer Genome Anatomy Project.

#1732772792539240-561: The Entrez system. Protein database maintains the text record for individual protein sequences, derived from many different resources such as NCBI Reference Sequence (RefSeq) project, GenBank, PDB, and UniProtKB/SWISS-Prot. Protein records are present in different formats including FASTA and XML and are linked to other NCBI resources. Protein provides the relevant data to the users such as genes, DNA/RNA sequences, biological pathways, expression and variation data, and literature. It also provides

The Bookshelf covers a wide range of topics including molecular biology , biochemistry , cell biology , genetics , microbiology , disease states from a molecular and cellular point of view, research methods, and virology . Some of
280-570: The alignments for the sequence of interest and the hits received with analogous BLAST scores for these. The Entrez Global Query Cross-Database Search System is used at NCBI for all the major databases such as Nucleotide and Protein Sequences, Protein Structures, PubMed, Taxonomy, Complete Genomes, OMIM, and several others. Entrez is both an indexing and retrieval system having data from various sources for biomedical research. NCBI distributed

The Bookshelf is a complement to the Entrez PubMed repository of peer-reviewed publication abstracts in that Bookshelf contents provide established perspectives on evolving areas of study and a context in which many disparate individual pieces of reported research can be organized. BLAST
320-515: The chosen format. Input sequences to the BLAST are mostly in FASTA or GenBank format while output could be delivered in a variety of formats such as HTML, XML formatting, and plain text. HTML is the default output format for NCBI's web-page. Results for NCBI-BLAST are presented in graphical format with all the hits found, a table with sequence identifiers for the hits having scoring related data, along with

Gene has been implemented at NCBI to characterize and organize
360-631: The information about genes. It serves as a major node in the nexus of the genomic map, expression, sequence, protein function, structure, and homology data. A unique GeneID is assigned to each gene record that can be followed through revision cycles. Gene records for known or predicted genes are established here and are demarcated by map positions or nucleotide sequences. Gene has several advantages over its predecessor, LocusLink, including, better integration with other databases in NCBI, broader taxonomic scope, and enhanced options for query and retrieval provided by
