UniProt functional annotation for P50106

UniProt code: P50106.

Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast).
Taxonomy: Eukaryota; Fungi; Dikarya; Ascomycota; Saccharomycotina; Saccharomycetes; Saccharomycetales; Saccharomycetaceae; Saccharomyces.
 
Function: DNA-dependent RNA polymerases catalyze the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase I (Pol I) which synthesizes ribosomal RNA precursors. RPA14 seems to play a role in the stability of subunits RPO26 and RPA43. In vitro, the RPA14-RPA43 subcomplex binds single- stranded RNA. {ECO:0000269|PubMed:12888498, ECO:0000269|PubMed:18160037, ECO:0000269|PubMed:24153182, ECO:0000269|PubMed:24153184}.
 
Subunit: Component of the RNA polymerase I (Pol I) complex consisting of 14 subunits: RPA135, RPA190, RPC40, RPA14, RPB5, RPO26, RPA43, RPB8, RPA12, RPB10, RPC19, RPC10, RPA49 and RPA34. The complex is composed of a horseshoe-shaped core containing ten subunits (RPA135, RPA190, RPB5, RPO26, RPB8, RPB10, RPC10, RPA12, RPC19 and RPC40) where RPA135 and RPA190 form the DNA-binding cleft. Outside of the core, RPA14 and RPA43 form the stalk that mediates interactions with transcription initiation factors and newly synthesized RNA. {ECO:0000269|PubMed:11918799, ECO:0000269|PubMed:18160037, ECO:0000269|PubMed:24153182, ECO:0000269|PubMed:24153184}.
Subcellular location: Nucleus, nucleolus {ECO:0000269|PubMed:14562095}.
Ptm: The N-terminus is blocked.
Miscellaneous: Present with 3100 molecules/cell in log phase SD medium. {ECO:0000269|PubMed:14562106}.
