Transcription initiation factor IIA subunit 1 is a protein that in humans is encoded by the GTF2A1 gene.[1][2]


GTF2A1 has been shown to interact with TATA binding protein[3][4][5][6][7] and TBPL1.[8][9]

Model organisms

Model organisms have been used in the study of GTF2A1 function. A conditional knockout mouse line called Gtf2a1tm1a(KOMP)Wtsi was generated at the Wellcome Trust Sanger Institute.[10] Male and female animals underwent a standardized phenotypic screen[11] to determine the effects of deletion.[12][13][14][15] Additional screens performed: - In-depth immunological phenotyping[16]
