Learn to use Entrez Protein, a comprehensive database of protein information brought to you by the National Institutes of Health and the National Library of Medicine's National Center for Biotechnology Information, or NCBI. You can use this resource to search for current protein information utilizing many of the handy features characteristic of NCBI's Entrez family of databases. These include many formatting, downloading and searching tools, such as "My NCBI", which allows you to customize your searches and results. Protein records contain extensive information including references, sequences, pre-computed homologs and many internal and external links.

You will learn:

  • to perform basic and advanced searches utilizing the many available tools and options
  • to understand the protein records and exploit the many internal and external links you are provided with
  • to explore some of the resources provided by the NCBI network of databases, such as "My NCBI"
