InterPro protein focus
Protein 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 sweetest thing
Our sugar consumption has reached to such a level that it carries health risks such as obesity, diabetes. In search for the sugar substitutes, scientists have found one of the sweetest proteins to date - thaumatin.
Don’t blame the cat - the toxoplasmosis effect
The parasite Toxoplasma gondii, the causative agent of toxoplasmosis, manipulates the behavior of rodents to ensure reaching its definitive host: the cat. Here we explore the biological mechanisms deployed to 'control' the host, and how this game of cat and mouse could be affecting you.
Dionysian mysteries - the aldehyde dehydrogenase (ALDH) family
Do you have friends that cannot handle alcoholic drinks? Just half a pint of beer or a few sips of wine, and their faces turn red, possibly with some hangover symptoms? In this article, we will learn more about the mystery behind this condition.

Wilson’s disease and the copper ATPase transporters
In the American TV series House, episode 'The Socratic Method', a mother seeming to suffer from schizophrenia is admitted to hospital. Let’s find out how House solves this case and how we can use InterPro to know more about the Wilson’s disease protein and its homologues.

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.

Relax and unwind: the RecQ DNA helicase family
When people go on holiday or travel for a conference, fitting all their clothes, books and a laptop into a small suitcase often presents a challenge. For eukaryotic cells, packing their lengthy genomic DNA into their relatively small nucleus presents a similar challenge.

Chemokine receptor type 4 (CXCR4): diseases, drugs and druggable target molecules
Chemokine Receptor type 4 (CXCR4) is of increasing interest as a drug target. This molecule is thought to be involved in many disease states including more than 23 types of cancer and several immunodeficiency disorders.

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.
