Representative sequences of Kex2-processed repeat proteins (KEPs) that function as fungal pheromones. Signal peptides were trimmed. a Ccg-4 of N. crassa, which is experimentally shown to be regulated by the mating type locus; its gene is not accompanied by DUF3328-domain-containing protein genes. b Ccg-4 homolog of Rutstroemia; its gene is accompanied by a DUF3328-domain containing protein gene. c PpgA of Aspergillus fumigatus; its gene is not accompanied by DUF3328-domain containing protein genes. The presumed pheromone peptides are shown in bold. The fragmented sequences cleaved by Kex2 containing no pheromone peptides but Y (in bold) are shown in red
