Gene Ontology Information

Protein Name	Cup9p
Description	Homeodomain-containing transcriptional repressor; regulates expression of PTR2, which encodes a major peptide transporter; imported peptides activate ubiquitin-dependent proteolysis, resulting in degradation of Cup9p and de-repression of PTR2 transcription; CUP9 has a paralog, TOS8, that arose from the whole genome duplication; protein abundance increases in response to DNA replication stress
GO Terms: Biological Process	level 7: regulation of DNA-templated transcription level 8: regulation of transcription by RNA polymerase II level 9: negative regulation of transcription by RNA polymerase II
GO Terms: Molecular Function	level 4: DNA-binding transcription factor activity, RNA polymerase II-specific level 5: DNA binding level 6: sequence-specific DNA binding level 6: RNA polymerase II-specific DNA-binding transcription factor binding level 8: RNA polymerase II cis-regulatory region sequence-specific DNA binding
GO Terms: Cellular Component	level 5: nucleus
