InterPro protein focus

Interpro protein focusProtein Focus (formally known as Protein of the Month) explores the function and family relationships of selected proteins from the InterPro database, aiming at a general audience. Each article introduces a different protein, exploring its biological function as it relates to other members of the protein family, examining common domain architectures and their biological distribution, and tying it in to a broader perspective on how the protein impacts today's medicine and the environment. The articles also serve as an introduction to the use of the InterPro database, exploring the relevant InterPro entries for each featured protein in detail, and relating them to the biological information discussed in the article. Links are provided to the PDB's Molecule of the Month, where the structural features of the proteins are explored in detail, and, when applicable, to the EXPASY Protein Spotlight to gain another view of the featured proteins.

The structure of the human 9-1-1 complex from PDB (3g65)Are we really related? The Rad9/Ddc1 family
Protein family classification is often achieved using computerised multiple protein sequence alignment and structural analysis. However, it's not always straightforward to define a protein family. In this article, we will take a look at an example-the Rad9/Ddc1 family.

Collagen 3D view Collagen: a ubiquitous, unsung protein
Collagen is a long, fibrous structural protein that is usually associated with cosmetic enhancements, movie star's lips and anti-aging lotions. Just as one hopes for these movie stars; there is much more to collagen than what appears on the surface. Collagen is the most abundant protein in mammals.
