| DESCRIPTION
When
yeast "a" and "a"
cells encounter mating pheromones of the opposite cell type
they induce genes necessary for mating, arrest the cell
cycle in G1, alter cell surface and nuclear determinants,
and also undergo dramatic morphological elongation into
pear shapes, affectionately termed schmooing. These alterations
prepare the yeast cells for mating and fusion to form stable
diploids. The a/a
diploids are not responsive to mating pheromone of either
type, but can be induced to undergo meiosis via nutrient
deprivation. The use of yeast mating pheromones has pioneered
the study of the cell cycle, cellular morphology, transcriptional
induction, as well as signal transduction pathways. Zymo
Research provides the a-factor peptide mating pheromone
as a ready to use liquid that has been optimized for both
activity and stability and is guaranteed to retain biological
function through multiple freeze-thaw cycles. |
