Structure and associated DNA-helicase activity of a general transcription initiation factor that binds to RNA polymerase II.

M Sopta1, Z F Burton, J Greenblatt.   

Abstract

RAP30/74 is a heteromeric general transcription initiation factor which binds to RNA polymerase II. Here we report that preparations of RAP30/74 contain an ATP-dependent DNA helicase whose probable function is to melt the DNA at transcriptional start sites. The sequence of the RAP30 subunit of RAP30/74 indicates that RAP30 may be distantly related to bacterial sigma factors.
