The Protein database is a collection of sequences from several sources, including translations from annotated coding regions in GenBank, RefSeq and TPA, as well as records from SwissProt, PIR, PRF, and PDB. Protein sequences are the fundamental determinants of biological structure and function.
CD-Search is NCBI's interface to searching the Conserved Domain Database with protein or nucleotide query sequences. It uses RPS-BLAST , a variant of PSI-BLAST, to quickly scan a set of pre-calculated position-specific scoring matrices ( PSSMs ) with a protein query.
Conserved Domain Architecture Retrieval Tool (CDART) Displays the functional domains that make up a given protein sequence. It lists proteins with similar domain architectures and can retrieve proteins that contain particular combinations of domains. Conserved Domain Search Service (CD Search)
NCBI's Protein resources include protein sequences and structures and related comparison and visualization tools, as well as databases and tools to predict and analyze functional domains. How to. Retrieve all protein sequences for an organism or taxon; Find the function of a protein; Find a gene homolog; View a protein 3D structure; more...
BlastP simply compares a protein query to a protein database. PSI-BLAST allows the user to build a PSSM (position-specific scoring matrix) using the results of the first BlastP run. PHI-BLAST performs the search but limits alignments to those that match a pattern in the query.
The Molecular Modeling Database (MMDB), as part of the Entrez system, facilitates access to structure data by connecting them with associated literature, protein and nucleic acid sequences, chemicals, biomolecular interactions, and more.
