HMR / HMR Overview
- Standard Name
- Systematic Name
- SGD ID
- Feature Type
- silent mating type cassette array
Mating-type cassette - right; unexpressed complete copy of the mating-type genes, silenced by the Sir2 histone deacetylase and its associated SIR1, SIR3 and SIR4 proteins; mating-type switching involves replacement of the Ya or Yalpha sequences present at the MAT locus with either the a or alpha genes located at one of the HM loci in a process stimulated by the HO endonuclease; sequence replacement occurs by gene conversion, leaving the donor unaltered
