2 GO annotations of cellular component

Name Definition
RNA polymerase I core factor complex A RNA polymerase I-specific transcription factor complex that is required for the transcription of rDNA by RNA polymerase I. In yeast the complex consists of Rrn6p, Rrn7p, and Rrn11p.
RNA polymerase transcription factor SL1 complex A RNA polymerase I-specific transcription factor complex that contains the TATA-box-binding protein (TBP) and at least three TBP-associated factors including proteins known in mammals as TAFI110, TAFI63 and TAFI48.

2 GO annotations of molecular function

Name Definition
metal ion binding Binding to a metal ion.
RNA polymerase I core promoter sequence-specific DNA binding Binding to a regulatory region composed of the transcription start site and binding sites for transcription factors of the RNA polymerase I transcription machinery. This site is often referred to as the CORE element. In mammalian cells, the CORE element functions in conjunction with the Upstream Control Element (UCE), while in fungi, protozoa, and plants, the CORE element functions without a UCE.

2 GO annotations of biological process

Name Definition
nucleolar large rRNA transcription by RNA polymerase I The synthesis of the large ribosomal RNA (rRNA) transcript which encodes several rRNAs, e.g. in mammals 28S, 18S and 5.8S, from a nuclear DNA template transcribed by RNA polymerase I.
RNA polymerase I preinitiation complex assembly The aggregation, arrangement and bonding together of proteins on promoter DNA to form the transcriptional preinitiation complex (PIC), the formation of which is a prerequisite for transcription from an RNA polymerase I promoter.
