The second volume of the Chromosomal Nonhistone Proteins treatise is dedicated in its entirety to the immunobiology of these proteins. Since immunological methods are adding rapidly to our knowledge of the specificity and intranuclear localization of chromosomal nonhistone proteins, a collection of chapters dealing with various aspects of this important area was judged appropriate.

The third volume of the Chromosomal Nonhistone Proteins treatise deals with the isolation and analysis of chromosomal proteins in general with specific features of these proteins in particular. In addition to the high mobility group (HMG) proteins, post synthetic modifications of chromosomal nonhistone proteins are discussed, together with some of their enzymatic properties DNA binding.

The first volume of the Chromosomal Nonhistone Proteins treatise presents a summary of the many attempts in the literature to correlate changes in chromosomal histone proteins specificity and metabolism with transcriptional regulations in eukaryotic cells.

The fourth and last volume of Chromosomal Nonhistone Proteins sequence attempts to confront these macromolecules with the major structural elements of the cell nucleus (with the exception of nucleosomes which will be treated separately in a later treatise). Proteins of the chromosomes, nucleoli, nuclear membrane, RNP particles, and nuclear matrix are described in detail.

This book endeavours to present an analysis of the current knowledge of the structure properties and possible functions of histones. The broad scope of this topic prevents the discussion of certain individual aspects in any detail. For this purpose, some of the more specialised review articles should be consulted. However, the present volume will contribute to a more general understanding of histone biochemistry and will provide stimulation, as well as source references, to the student of the cell nucleus and its functions.
