Evidence for naming the protein now on non-redundant refseq records (WP_ accessions)


We are now showing the curated evidence used for assigning names and, if possible, gene symbols, publications, and Enzyme Commission numbers on nearly 70% (83 million) microbial RefSeq proteins. This evidence includes a hierarchical collection of curated Hidden Markov Model (HMM)-based and BLAST-based protein families, and conserved domain architectures.

Human genome annotation will be updated every 2 months


NCBI will be updating the human genome RefSeq annotation more frequently to incorporate improvements made to genes and transcripts by RefSeq curation experts. Faster updates will allow us to include the latest datasets.

In the past, we’ve produced a full re-annotation of the human genome about once a year. The last full annotation, Homo sapiens Annotation Release 109, was in March 2018. A full annotation is produced by two main processes:
