NOMENCLATURE CONFLICT NOTE
| Name | Relevance | Description |
|---|---|---|
| TUF1 | Nomenclature conflict | TUF1 has been used in the literature to refer to both RAP1/YNL216W (Shore, D. and Nasmyth, K. (1987) Cell 51:721; PMID:3315231), which encodes a transcription factor and telomere capping protein, and TUF1/YOR187W (Nagata, S. et al. (1983) Proc. Nat. Acad. Sci. 80:6192; PMID:6353412), which encodes mitochondrial translation elongation factor Tu. |
SUMMARY PARAGRAPH for RAP1
RAP1 (Repressor Activator Protein) encodes an essential protein involved in many diverse, some seemingly contradictory, processes in S. cerevisiae, including telomere maintenance, transcriptional silencing (repression) of the silent mating loci HML and HMR, and high level transcriptional activation of genes encoding ribosomal proteins and glycolytic enzymes (3, 4, 5, 6). In these various roles, the underlying function of Rap1p is to bind DNA in a sequence specific manner, often regulating the chromatin structure in the region where it binds (7, 8). Rap1p binds extensively in telomeric regions, where its function is related to both transcriptional silencing and telomere maintenance (9). In its role as a transcription activating factor, the largest group of target genes are those that encode ribosomal proteins (6). In rapidly growing yeast cells, the transcription rate of these genes is extremely high, accounting for about twenty percent of the total mRNA content of the cell (10). Rap1p is known to be required for the transcription of several non-ribosomal protein genes, including HIS4 (11), ENO1 and ENO2 (12), and is implicated in transcriptional regulation of 185 additional genes (6).
