β¦ Synopsis
Histone and non-histone-proteins (NHP) are proteins with a specific affinity to DNA; each group is involved in the regulation of gene expression in its own way. To investigate molecular biologic processes at psoriasis, DNA-binding proteins (DBP) were isolated from psoriatic scales. During this work the proportions of histone and NHP of the DBP fractions were examined. Using two different methods (Bio Rex 70-chromatography and isoelectrofocussing), it was found that the isolated DBP contain only acidic proteins. Likewise, the composition of amino acids is comparable with those of acidic, nuclear proteins of other tissues. Thus the isolated DBP represent to its greatest extent acidic, chromosomal NHP, which obviously are derived from the preserved nuclei of the parakeratotic scale layer.

The composition of DNA-binding proteins (DBP) was shown to be tissue-specific and to vary at different stages of gene expression. As the accelerated epidermopoesis in psoriasis indicates changed gene activities, DBP of psoriatic scales were compared with those of normal human epidermis, dermis and h
