Multiple epigenetic events regulate mating-type switching of fission yeast
Novartis Found Symp.
1998.
Abstract
Two epigenetic events at mat1, one of which is DNA strand specific, are required to initiate recombination during mating-type switching. The third, a chromosomally borne imprinted event at the mat2/3 interval regulates silencing and directionality of switching, and prohibits interchromosomal recombination. We speculate that the unit of inheritance in the mat2/3 interval is both DNA plus its associated chromatin structure. Such a control is likely to be essential in maintaining particular states of gene expression during development.
