Immunochemical approaches to the study of histone H1 and high mobility group chromatin proteins.
This review is an attempt to summarize all existing data on histone H1 and high mobility group proteins obtained with immunochemical methods. The following issues are treated consecutively: production of specific antisera to these protein groups, antigenic structure of the polypeptide chains, use of antibodies for the identification, the quantitative estimation and the study of the tissue- and species-specificity of the proteins. Special attention is devoted to the studies of the localization of the respective antigens in the cell, the nucleus, the chromosomes and the interphase chromatin. The use of specific antibodies for the elucidation of the role these proteins play in such basic cellular processes as proliferation and differentiation, replication and transcription is also discussed. It becomes clear that the use of immunochemical approaches in the study of specific chromatin proteins both at the level of the protein molecule and at the level of chromatin can be a powerful tool for the resolution of a number of specific problems. The field is very promising and will undoubtedly develop intensely in the nearest future.
