transcription initiation factor IIA beta (TFIIA p19 subunit)

Function

• TFIIA-alpha & TFIIA-beta derived from same gene transcript
• alpha & beta subunits are postranslationally produced from the precursor form by TASP1
• the cleavage promotes proteosomal degradation

Structure

• TFIIA is a heterodimer of the large unprocessed subunit 1 & a small subunit gamma
• originally believed to be a heterotrimer of an alpha (p35), a beta (p19) & a gamma subunit (p12)

More general terms

• transcription initiation factor IIA subunit 1

Additional terms

• TFIIA-alpha & beta-like factor; general transcription factor II A, 1-like factor (GTF2A1L, ALF, GTF2A1LF)

Component of

• transcription factor IIA
