Conserved domain database

CDD has been available publicly for over 20 years and has grown conserved domain database during that time. Maintaining an archive of pre-computed annotation continues to be a challenge and has slowed down the cadence of CDD releases. CDD aims to collect a comprehensive set of protein and domain family models, and it does allow for considerable redundancy in the model set, to ensure good coverage of the protein space. Models that provide significantly overlapping annotation are clustered into protein domain superfamilies, and when domain annotation fails to exceed critical model-specific score thresholds, CDD by default reports superfamily annotation rather than individual model hits, conserved domain database.

Conserved domain database

Identify the putative function of a protein sequence. Identify a protein's classification based on domain architecture. Identify the amino acids in a protein sequence that are putatively involved in functions such as binding or catalysis, as mapped from conserved domain annotations to the query sequence. View a query protein sequence embedded within the multiple sequence alignment of a domain model. Interactively view the 3D structure of a conserved domain. Find other proteins with similar domain architecture. Interactively view the phylogenetic sequence tree for a conserved domain model of interest with or without a query sequence embedded. Conserved Domains and Protein Classification. HOW TO. CDD is a protein annotation resource that consists of a collection of well-annotated multiple sequence alignment models for ancient domains and full-length proteins. How To. The results of CD-Search are presented as an annotation of protein domains on the user query sequence illustrated example , and can be visualized as domain multiple sequence alignments with embedded user queries. High confidence associations between a query sequence and conserved domains are shown as specific hits. Batch CD-Search serves as both a web application and a script interface for a conserved domain search on multiple protein sequences , accepting up to 4, proteins in a single job. It enables you to view a graphical display of the concise or full search result for any individual protein from your input list, or to download the results for the complete set of proteins.

Data citation guideline. Journal Article. In molecular evolution such domains may have been utilized as building blocks, and may have been recombined in different arrangements to modulate protein function.

Toggle navigation. Repository details Conserved Domain database. General Institutions Terms Standards Name of repository. Additional name s. Repository URL. Subject s. The Conserved Domain Database is a resource for the annotation of functional units in proteins.

This page provides quick start guides for some common types of searches. The CDD Help document provides detailed descriptions of the database content, search system, and display formats. Once records of interest are retrieved, follow Entrez's "Links" to discover associations among previously disparate data. Conserved Domains and Protein Classification. HOW TO. How to use CDD: examples. Identify the putative function of a protein sequence. Identify a protein's classification based on domain architecture. Identify the specific amino acids in a protein sequence that are putatively involved in functions such as binding or catalysis , as mapped from conserved domain annotations to the query sequence.

Last update. Novel beta-propeller of the BTB-Kelch protein Krp1 provides a binding site for Lasp-1 that is necessary for pseudopodial extension. David I. Conserved Domains and Protein Classification. Conserved Domains and Protein Classification. Please check for further notifications by email. We continue to add novel domain family models to the collection and to establish hierarchical classifications of selected protein domain families where they will have a significant impact on protein naming by domain architecture. Issue Section:. How To. Figure 1. Comparison of sequence and structure alignments for protein domains. New issue alert. However, details of the annotation for numerous individual protein sequences have changed. I agree to the terms and conditions. Search by text word.

The Conserved Domain Database CDD is a database of well-annotated multiple sequence alignment models and derived database search models, for ancient domains and full-length proteins.

RefSeq: expanding the prokaryotic genome annotation pipeline reach with protein family model curation. The national center for biotechnology information's protein clusters database. Comparison of sequence and structure alignments for protein domains. Search Menu. Categories : Biological databases Protein structure Protein domains. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide. At this time, about 60 million bacterial RefSeq proteins are named via SPARCLE out of million total bacterial proteins and million proteins with naming evidence provided. Structural motifs are not necessary functional, but provide more detailed annotation on query sequences. The major focus of ongoing work at CDD is to ensure sustainability of the data flow and public services. In early , CDD version v3.
