Description

Gap junctions are present in nearly all tissues, regardless of their embronic origin and have long been of great interest to scientists from many different disciplines. The international meeting on which this book is based brought together 157 scientists from 12 countries and almost as many scientific disciplines. The papers presented at the meeting were reviewed and updated prior to publication in this book. The seven parts of the book progress from general topics to the more specific ones (role of gap junctions in various tissues, regulation and biochemistry, and cancer).

Table of Contents

Prologue. Contributors. Part I. The Connexin Protein Family Divergent properties of different connexins expressed in Xenopus oocytes. Identification of novel connexins by reduced stringency hybridization and PCR amplification using degenerate primers. Affinities between connexins. Expression of Cx43 in rat and mouse liver. The mouse connexin gene family. Part II. Structure Atomic force microscopy of gap junctions. Structure and design of cardiac gap-junction membrane channels. Biochemistry of gap-junction channels. In vitro assembly of lens gap junctions. Part III. Hemichannels Connexins, gap junction proteins, and ATP-induced pores in macrophages. Connexin-46 forms gap-junctional hemichannels in Xenopus oocytes. Solitary retinal horizontal cells express hemi-gap-junction channels. Part IV.
