Evolutionarily conserved motifs and protein binding elements in the 5' region of the chromosomal protein HMG-14 gene.
Although the structure of several genes coding for chromosomal proteins HMG-14 and HMG-17 has been determined, the mechanisms regulating the expression of these genes has not yet been examined. Toward this goal, we have cloned and sequenced a fragment containing the first three exons and 956 bp upstream from the start of translation of the functional mouse HMG-14 gene. Comparison of this sequence to the known sequence of the human HMG-14 gene revealed the presence of five distinct blocks of high sequence identity flanking the start of transcription and the CAAT box. DNase I and mobility-shift analysis identified a DNA region, downstream from the start of transcription, which may be important for the formation of a stable protein-DNA complex. Affinity chromatography on columns containing oligonucleotides corresponding to this sequence indicates that this region is a protein binding site.
