EOG8V71ZF GO:0005672 24/87 transcription factor TFIIA complex cellular_component "A component of the transcription machinery of RNA Polymerase II. In humans, TFIIA is a heterotrimer composed of an alpha (P35), beta (P19) and gamma subunits (P12)." [GOC:jl, PMID:17560669] EOG8V71ZF GO:0006367 24/87 transcription initiation from RNA polymerase II promoter biological_process "Any process involved in the assembly of the RNA polymerase II preinitiation complex (PIC) at an RNA polymerase II promoter region of a DNA template, resulting in the subsequent synthesis of RNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. Promoter clearance, or release, is the transition between the initiation and elongation phases of transcription."

[GOC:jl, GOC:txnOH, http://www.mblab.gla.ac.uk/, PMID:16858867] EOG8V71ZF GO:0045944 1/87 positive regulation of transcription from RNA polymerase II promoter biological_process "Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter." [GOC:go_curators, GOC:txnOH] EOG8V71ZF GO:0005634 1/87 nucleus cellular_component "A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent." [GOC:go_curators] EOG8V71ZF GO:0001129 1/87 RNA polymerase II transcription factor activity, TBP-class protein binding, involved in preinitiation complex assembly molecular_function "Interacting selectively and non-covalently with a member of the class of TATA-binding proteins (TBP), including any of the TBP-related factors (TRFs), to facilitate the aggregation, arrangement and bonding together of proteins on RNA polymerase II promoter DNA to form the transcriptional preinitiation complex (PIC), the formation of which is a prerequisite for transcription by RNA polymerase." [GOC:txnOH, PMID:16858867] EOG8V71ZF GO:0001094 1/87 TFIID-class transcription factor binding molecular_function "Interacting selectively and non-covalently with a basal RNA polymerase II transcription factor of the TFIID class, one of the factors involved in formation of the preinitiation complex (PIC) by RNA polymerase II and defined as a basal or general transcription factor."
