The conserved domain database in 2023

NLM's conserved domain database (CDD) is a collection of protein domain and protein family models constructed as multiple sequence alignments. CDD curation staff builds hierarchical classifications of large protein domain families, adds models for novel domain families via surveillance of the protein 'dark matter' that currently lacks annotation, and now spends considerable effort on providing names and attribution for conserved domain architectures.

• 1 Its main purpose is to provide annotation for protein and translated nucleotide sequences with the location of domain footprints and associated functional sites, and to define protein domain architecture as a basis for assigning gene product names and putative/predicted function.
• 2 CDD has been available publicly for over 20 years and has grown substantially during that time.
• 3 Maintaining an archive of pre-computed annotation continues to be a challenge and has slowed down the cadence of CDD releases.

Mathematical breakthroughs form the theoretical backbone of science, cryptography, data analysis, and engineering.
