A new dataset of pheromone and pheromone-gene structures from the ciliate, Euplotes crassus.

ABSTRACT: Like many other organisms, ciliates communicate and interact socially via diffusible chemical signals, named pheromones, that are functionally associated with a genetic mating-type mechanism of cell self/not-self recognition. In Euplotes species, pheromones form species-specific families of small, globular, and disulfide-rich proteins folding into exclusively helical secondary structures. Each is specified by one of a series of high-multiple alleles that are inherited in Mendelian fashion with relationships of co-dominance at the so-called mat genetic locus of the cell transcriptionally inert micronuclear genome, and expressed in the transcriptionally active macronuclear genome as individual DNA molecules in which the central coding region is flanked by 5'-leader and 3'-trail
