Protein kinases are enzymes which add phosphate groups to proteins. They are important in biological processes such as cell signalling and can be divided into a number of groups based on function and the similarity of the amino acid sequence.

Kinomer is a multilevel HMM library that models these protein kinase groups. It allows accurate identification of protein kinases and classification to the appropriate kinase group.

This website provides access to the Kinomer HMM library to classify your own sequences, and a curated database of kinases identified with Kinomer from many sequenced genomes.
