Kinases from the CAMK group mainly cluster together. In addition, the following kinases from other kinase groups are included in our CAMK-like cluster: Kinases from the STE group are assigned mostly to a single cluster that is, however, shared with kinases from many other kinase groups. The STE kinases MAP2K [1,4,6,7] and OSR1 are separated from the other STE kinases.
