Regulation of the human MHC class I HLA-A11 promoter is governed by a
complex array of regulatory elements. One of these elements, shown here to
be critical for the transcriptional activity of the promoter, was used to
screen a lambda gt11 library and allowed the identification of a cDNA which
coded for the zinc finger protein ZFX. ZFX was shown to bind the sequences
AGGGCCCCA and AGGCCCCGA, located respectively at positions -271 to -263 and
-242 to -234 of the HLA-A11 promoter, with similar affinities through its
three C-terminal zinc fingers. ZFX575, a short isoform of ZFX, activates
transcription from the HLA-All promoter in a Leydig cell line.
