B PF00575 S1 S1 RNA binding domain Domain The S1 domain occurs in a wide range of RNA associated proteins. It is structurally similar to cold shock protein which binds nucleic acids. The S1 domain has an OB-fold structure. PFAM PF00575
B PF03876 SHS2_Rpb7-N SHS2 domain found in N terminus of Rpb7p/Rpc25p/MJ0397 Domain 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]. PFAM PF03876
