[[http://www.uniprot.org/uniprot/RAP1_YEAST RAP1_YEAST]] Essential regulatory protein in yeast whose DNA-binding sites are found at three types of chromosomal elements: promoters, silencers, and telomeres. RAP1 is also involved in the regulation of telomere structure, where its binding sites are found within the terminal poly[C(1-3)A] sequences. The opposite regulatory functions of RAP1 are not intrinsic to its binding sites but, instead, result from interactions with different factors at promoters and silencers. RAP1 associates with SIR3 and SIR4 proteins to form a DNA-binding complex that initiates the repression at the HM loci and telomeres. May also target the binding of RIF1 and RIF2 to silencers and telomeres. Forms with GCR1 a transcriptional activation complex that is required for expression of glycolytic and ribosomal gene.

Rap1 (repressor-activator protein 1) from Saccharomyces cerevisiae, containing a BRCT domain at its N-terminus, is a multifunctional protein that controls telomere function, silencing, and the activation of glycolytic and ribosomal protein genes. In this work, we determined the solution structure of Rap1 BRCT domain, which contains three beta-strands and three alpha-helices. Structural comparison indicated that Rap1 BRCT domain adopts a global fold similar to other BRCT domains, implying some common structural aspects of BRCT domain family. On the other hand, Rap1 BRCT domain displays structural characteristics significantly different from other BRCT domains in that Rap1 BRCT domain adopts a rather flexible conformation with less secondary structure elements, revealing a novel fold of the BRCT domain family.
