We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Function

[MER11_EUPRA] Mating ciliate pheromones (or gamones) are diffusible extracellular communication signals that distinguish different intraspecific classes of cells commonly referred to as 'mating types'. They prepare the latter for conjugation by changing their cell surface properties.

Publication Abstract from PubMed

The NMR solution structure of the pheromone Er-11, a 39-residue protein from the ciliated protozoan Euplotes raikovi, was calculated with the distance geometry program DIANA from 449 NOE upper distance constraints and 97 dihedral angle constraints, and the program OPAL was employed for structure refinement by molecular mechanics energy minimization in a water bath. For a group of 20 conformers used to characterize the solution structure, the average of the pairwise RMS deviations from the mean structure calculated for the backbone heavy atoms N, C alpha, and C' of residues 2-38 was 0.30 A. The molecular architecture is dominated by an up-down-up bundle of three short helices with residues 2-9, 12-19, and 22-32, which is closely similar to the previously determined structures of the homologous pheromones Er-1, Er-2, and Er-10. This finding provides structural evidence for the capability shown by these pheromones to compete with each other in binding reactions to their cell-surface receptors.
