Download or read book Cytoplasmic fate of messenger RNA written by Philippe Jeanteur and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among all cellular RNA species of the three main types, ribosomal RNA, transfer RNA or messenger RNA, be they from prokaryotic or eukaryotic organisms, the prokaryotic mRNA is unique in that it has no precursor and is synthesized in the same mature form as it is translated into proteins. In fact, ribosomes join the nascent mRNA chain and engage in protein synthesis long before its transcription is complete. Provisions are even made for slowing down the ribo somes at some sites to prevent them from catching up with the RNA-polymerase. Of course, such a situation is only possible in the prokaryotic world where there is no such thing as a nuclear mem brane physically secluding the transcription process from the cy toplasm where translation is restricted. Quite in the opposite extreme, the eukaryotic pre-messenger RNA has to suffer many and sometimes drastic steps of maturation (capping, polyadenylation, splicing, edition) before the decision is made to export it to the cytoplasm. That is where it enters the scope of this book. Once in the cytoplasm, many options are still open to it: its entrance into polysomes may be delayed (as it is in unfertilized eggs) or merely prohibited (ferritin mRNA in iron-starved cells), directed to specific locations within the cytoplasm or be more or less rapidly degraded. During gametogenesis and early development, translational control is probably the most significant level of gene expression.

Download or read book Development written by Vincenzo E.A. Russo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of the molecular genetic analysis of development similar mechanisms for the regulation of gene expression are found in a wide range of organisms. In "Development - the Molecular Genetic Approach" these common mechanisms as well as the specific events leading to a differentiated cell are described. Particular items treated are, for example, how asymmetry is achieved, how cell size is determined, how cell division is controlled, how cell lineage influences development, how cells know their position, and how cells communicate during development.

Download or read book Molecular Biology of RNA written by David Elliott and published by Oxford University Press. This book was released on 2017-01-31 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: RNA plays a central, and until recently, somewhat underestimated role in the genetics underlying all forms of life on earth. This versatile molecule not only plays a crucial part in the synthesis of proteins from a DNA template, but is also intrinsically involved in the regulation of gene expression, and can even act as a catalyst in the form of a ribozyme. This latter property has led to the hypothesis that RNA - rather than DNA - could have played an essential part in the origin of life itself. This landmark text provides a systematic overview of the exciting and rapidly moving field of RNA biology. Key pioneering experiments, which provided the underlying evidence for what we now know, are described throughout, while the relevance of the subject to human disease is highlighted via frequent boxes. For the second edition of Molecular Biology of RNA, more introductory material has been incorporated at the beginning of the text, to aid students studying the subject for the first time. Throughout the text, new material has been included - particularly in relation to RNA binding domains, non-coding RNAs, and the connection between RNA biology and epigenetics. Finally, a new closing chapter discusses how exciting new technologies are being used to explore current topical areas of research.

Download or read book Oocytes written by Malgorzata Kloc and published by Springer. This book was released on 2017-08-02 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book combines the most recent knowledge on the maternal, i.e. oocyte/egg-specific, molecules and processes. The volume covers the most recent advances in a plethora of subjects such as: maternal transfer of immunity, localized RNAs functions and mechanisms of RNA localization, transcriptional repression of maternal messages, maternal inheritance and maternal role of CRISPR/Cas9-based genome editing, chromatin remodeling and epigenetic modifications, maternal function of nucleosomes, maternal mitochondria and energy supply, role of bacterial symbionts and their maternal transmission, acquisition of oocyte polarity and evolution of maternal effect genes, germ plasm and oosome origin and functions, mechanisms of oocyte activation and soma germ cells communication. Currently, no other book on the market combines such a comprehensive list of subjects in one volume. Moreover, the information provided is a cross-section through oocytes from various invertebrate and vertebrate species, which is another unique feature of this book. The readers, therefore, get a completely new and invaluable perspective on all covered subjects.

Download or read book Toxic Plant Proteins written by J. Michael Lord and published by Springer Science & Business Media. This book was released on 2010-07-20 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many plants produce enzymes collectively known as ribosome-inactivating proteins (RIPs). RIPs catalyze the removal of an adenine residue from a conserved loop in the large ribosomal RNA. The adenine residue removed by this depurination is crucial for the binding of elongation factors. Ribosomes modified in this way are no longer able to carry out protein synthesis. Most RIPs exist as single polypeptides (Type 1 RIPs) which are largely non-toxic to mammalian cells because they are unable to enter them and thus cannot reach their ribosomal substrate. In some instances, however, the RIP forms part of a heterodimer where its partner polypeptide is a lectin (Type 2 RIPs). These heterodimeric RIPs are able to bind to and enter mammalian cells. Their ability to reach and modify ribosomes in target cells means these proteins are some of the most potently cytotoxic poisons found in nature, and are widely assumed to play a protective role as part of the host plant’s defenses. RIPs are able to further damage target cells by inducing apoptosis. In addition, certain plants produce lectins lacking an RIP component but which are also cytotoxic. This book focuses on the structure/function and some potential applications of these toxic plant proteins.
