AGO2 and its partners: a silencing complex, a chromatin modulator, and new features.
AGO2 is the only member with catalytic activity in Argonaute family and contains four functional core domains, which are N domain, PAZ domain, MID domain, and PIWI domain from N-terminal to C-terminal. In traditional view, AGO2 serves as the catalytic engine of the RNA induced silencing complex and plays an important role in small RNAs guided post transcriptional gene silencing, including mRNA degradation and translational repression. Moreover, AGO2 also plays multiple roles in gene regulation processes in nuclei, such as chromatin remodeling, transcriptional repression and activation, double-strand break repair and alternative splicing. Recent studies have also implicated AGO2 in several other cellular processes, including alternative polyadenylation, translational activation, and transposon repression.
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.
