At its heart, each individual InterPro entry consists of one or more member database signatures that are characteristic of the same protein family, domain or sequence feature. The entry is given a name and a unique InterPro identifier. It is also annotated with additional information, which can be found in different sections on the entry page.
For example, Figure 4 below shows the InterPro entry for the type 2 malate dehydrogenase protein family. The entry has a name (malate dehydrogenase, type 2) and identifier (IPR010945). The contributing signatures are shown on the right-hand side, with links to the signatures on the individual member database web sites. A descriptive abstract explains what these proteins are and what their function is. It also provides links to publications in PubMed for more detailed information. A set of GO terms is also provided, which describe the characteristics of the proteins matched by the entry.
