Heat maps indicating the species for which orthologues exist for human proteins containing LRR, PDZ, and SH2 domains. For each human LRR protein (row), each column corresponds to a species in which an orthologue of the protein exists. The species are partitioned into the taxonomically related groups indicated, and the species within each group are arranged from left to right in decreasing order of orthologue count. The specific human LRR proteins which are strongly conserved in fungi are highlighted. The protein subsets indicated by the numbers 1 through 6 are described in the text.
