Molecular analysis of the SNF2/SWI2 protein family member MOT1, an ATP-driven enzyme that dissociates TATA-binding protein from DNA.

Abstract excerpt

MOT1 is an essential Saccharomyces cerevisiae protein and a member of the SNF2/SWI2 family of ATPases. MOT1 functions by removing TATA-binding protein (TBP) from DNA, and as a consequence, MOT1 can regulate transcription both in vitro and in vivo. Here we describe the in vivo and in vitro activities of MOT1 deletion and substitution mutants. The results indicate that MOT1 is targeted to TBP both in vitro and in...
