SURVEY AND SUMMARY The interaction networks of structured RNAs

نویسنده

چکیده

All pairwise interactions occurring between bases which could be detected in three-dimensional structures of crystallized RNA molecules are annotated on new planar diagrams. The diagrams attempt to map the underlying complex networks of base–base interactions and, especially, they aim at conveying key relationships between helical domains: co-axial stacking, bending and all Watson–Crick as well as non-Watson–Crick base pairs. Although such wiring diagrams cannot replace full stereographic images for correct spatial understanding and representation, they reveal structural similarities as well as the conserved patterns and distances between motifs which are present within the interaction networks of folded RNAs of similar or unrelated functions. Finally, the diagrams could help devising methods for meaningfully transforming RNA structures into graphs amenable to network analysis.

P2P Network Trust Management Survey

Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...

The Consistency and Construct Validity of Wolf Motor Function Test With Functional Variables and SF-36 Questionnaire in Iranian Stroke Patients

Background: One of the most important indicators for assessing the validity of a scale is the determination of the construct validity of that scale. Since no standard gold test exists to measure the upper limb function in patients with stroke, the study of the construct validity of the Wolf Motor Function Test (WMFT) is of particular importance. Objectives: To evaluate the construct validity o...

SURVEY AND SUMMARY Experimental approaches to identify non-coding RNAs

Cellular RNAs that do not function as messenger RNAs (mRNAs), transfer RNAs (tRNAs) or ribosomal RNAs (rRNAs) comprise a diverse class of molecules that are commonly referred to as non-protein-coding RNAs (ncRNAs). These molecules have been known for quite a while, but their importance was not fully appreciated until recent genome-wide searches discovered thousands of these molecules and their ...
