This is OB domain found in RPA43 proteins (DNA-directed RNA polymerase I subunit RPA43, also known as A43) in yeast. Functional analysis of RNA polymerase I show that, subunits A14 and A43 form the heterodimer A14/43, which is distantly related to Rp ...
This is OB domain found in RPA43 proteins (DNA-directed RNA polymerase I subunit RPA43, also known as A43) in yeast. Functional analysis of RNA polymerase I show that, subunits A14 and A43 form the heterodimer A14/43, which is distantly related to Rpb4/7 in Pol II and C17/25 in Pol III [1]. Crystal structure analysis show that A43-A14 heterodimer forms the stalk that provides a platform for initiation factors and interacts with newly synthesized RNA [3].
SHS2 domain found in N terminus of Rpb7p/Rpc25p/MJ0397
Rpb7 bind to Rpb4 to form a heterodimer. This complex is thought to interact with the nascent RNA strand during RNA polymerase II elongation[1]. This family includes the homologs from RNA polymerase I and III. In RNA polymerase I, Rpa43 is at leas ...
Rpb7 bind to Rpb4 to form a heterodimer. This complex is thought to interact with the nascent RNA strand during RNA polymerase II elongation[1]. This family includes the homologs from RNA polymerase I and III. In RNA polymerase I, Rpa43 is at least one of the subunits contacted by the transcription factor TIF-IA [2]. The N terminus of Rpb7p/Rpc25p/MJ0397 has a SHS2 domain that is involved in protein-protein interaction [3].
