Abstract
Pancreatic-type ribonucleases (ptRNases) are a large family of vertebrate-specific secretory endoribonucleases. These enzymes catalyze the degradation of many RNA substrates and thereby mediate a variety of biological functions. Though the homology of ptRNases has informed biochemical characterization and evolutionary analyses, the understanding of their biological roles is incomplete. Here, we review the functions of two ptRNases: RNase 1 and angiogenin. RNase 1, which is an abundant ptRNase with high catalytic activity, has newly discovered roles in inflammation and blood coagulation. Angiogenin, which promotes neovascularization, is now known to play roles in the progression of cancer and amyotrophic lateral sclerosis, as well as in the cellular stress response. Ongoing work is illuminating the biology of these and other ptRNases.
期刊介绍：
As the discipline of biochemistry and molecular biology have greatly advanced in the last quarter century, significant contributions have been made towards the advancement of general medicine, genetics, immunology, developmental biology, and biophysics. Investigators in a wide range of disciplines increasingly require an appreciation of the significance of current biochemical and molecular biology advances while, members of the biochemical and molecular biology community itself seek concise information on advances in areas remote from their own specialties.
Critical Reviews in Biochemistry and Molecular Biology believes that well-written review articles prove an effective device for the integration and meaningful comprehension of vast, often contradictory, literature. Review articles also provide an opportunity for creative scholarship by synthesizing known facts, fruitful hypotheses, and new concepts. Accordingly, Critical Reviews in Biochemistry and Molecular Biology publishes high-quality reviews that organize, evaluate, and present the current status of high-impact, current issues in the area of biochemistry and molecular biology.
Topics are selected on the advice of an advisory board of outstanding scientists, who also suggest authors of special competence. The topics chosen are sufficiently broad to interest a wide audience of readers, yet focused enough to be within the competence of a single author. Authors are chosen based on their activity in the field and their proven ability to produce a well-written publication.
