RNA polymerase III subunit Rpc25; Rpc25 is a strongly conserved subunit of RNA polymerase III and has homology to Rpa43 in RNA polymerase I, Rpb7 in RNA polymerase II and the archaeal RpoE subunit. Rpc25 is required for transcription initiation and is not essential for the elongating properties of RNA polymerase III.

 2-81 3.86e-42

RNAP_III_Rpc25_N: Rpc25, N-terminal ribonucleoprotein (RNP) domain. Rpc25 is a subunit of eukaryotic RNA polymerase (RNAP) III and is homologous to Rpa43 of eukaryotic RNAP I, Rpb7 of eukaryotic RNAP II, and RpoE of archaeal RNAP. Rpc25 has two domains, an N-terminal RNP domain and a C-terminal oligonucleotide-binding (OB) domain, both of which are thought to bind single-stranded RNA. Rpc25 heterodimerizes with Rpc17 and plays an important role in transcription initiation. RNAP III transcribes diverse structural and catalytic RNAs including 5S ribosomal RNAs, tRNAs, and a small number of snRNAs involved in RNA and protein synthesis.

 2-81 5.56e-38

RNAP_Rpb7_N_like: This conserved domain represents the N-terminal ribonucleoprotein (RNP) domain of the Rpb7 subunit of eukaryotic RNA polymerase (RNAP) II and its homologs, Rpa43 of eukaryotic RNAP I, Rpc25 of eukaryotic RNAP III, and RpoE (subunit E) of archaeal RNAP. These proteins have, in addition to their N-terminal RNP domain, a C-terminal oligonucleotide-binding (OB) domain. Each of these subunits heterodimerizes with another RNAP subunit (Rpb7 to Rpb4, Rpc25 to Rpc17, RpoE to RpoF, and Rpa43 to Rpa14). The heterodimer is thought to tether the RNAP to a given promoter via its interactions with a promoter-bound transcription factor.The heterodimer is also thought to bind and position nascent RNA as it exits the polymerase complex.

RpoE heterodimerizes with RpoF, another RNA polymerase subunit. RpoE has an elongated two-domain structure that includes an N-terminal RNP domain and a C-terminal oligonucleotide-binding (OB) domain. Both domains of RpoE bind single-stranded RNA.

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. 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. The N terminus of Rpb7p/Rpc25p/MJ0397 has a SHS2 domain that is involved in protein-protein interaction.

RNAP_II_Rpb7_N: Rpb7, N-terminal ribonucleoprotein (RNP) domain. Rpb7 is a subunit of eukaryotic RNA polymerase (RNAP) II that is homologous to Rpc25 of RNAP III, RpoE of archaeal RNAP, and Rpa43 of eukaryotic RNAP I. Rpb7 heterodimerizes with Rpb4 and this heterodimer binds the 10-subunit core of RNAP II, forming part of the floor of the DNA-binding cleft. Rpb7 has two domains, an N-terminal RNP domain and a C-terminal oligonucleotide-binding (OB) domain, both of which bind single-stranded RNA. Rpb7 is thought to interact with the nascent RNA strand as it exits the RNAP II complex during transcription elongation. The Rpb7/Rpb4 heterodimer is also thought to serve as an upstream interface between the C-terminal domain of Rpb1 and the transcription factor IIB (TFIIB), recruiting pol II to the pol II promoter.
