negative regulation of transcription by transcription factor catabolism
Any process that stops, prevents, or reduces the frequency, rate or extent of DNA-dependent transcription using a mechanism that involves the catabolism of a sequence-specific DNA-binding transcription factor by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome.
