Protein

Centromere-binding protein 1

Gene

CBF1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Required for chromosome stability and methionine prototrophy. It is involved in chromosomal segregation. Binds to a highly conserved DNA sequence (5'-RTCACRTG-3'), called CDEI, found in centromeres and in several promoters. DNA-binding activity is enhanced by MET28. Required as an auxiliary factor for transcriptional activation of sulfur metabolism together with MET4 and MET28.2 Publications

Miscellaneous

Present with 6890 molecules/cell in log phase SD medium.1 Publication
