Crystallographic analysis of G-clamp-RNA complex assisted by large scale RNA-binding profile.

We present the X-ray crystal structure of a complex between a G-clamp and an internal loop motif of pre-mir-125a, selected from high affinity RNAs identified in a large-scale RNA-binding profile. This X-ray crystal structure reveals that the G-clamp interacts with three distinct guanine bases, forming robust bonds through hydrogen bonding and stacking interactions.

Large-scale analysis of small molecule-RNA interactions using multiplexed RNA structure libraries.

The large-scale analysis of small-molecule binding to diverse RNA structures is key to understanding the required interaction properties and selectivity for developing RNA-binding molecules toward RNA-targeted therapies. Here, we report a new system for performing the large-scale analysis of small molecule-RNA interactions using a multiplexed pull-down assay with RNA structure libraries. The system profiled the RNA-binding landscapes of G-clamp and thiazole orange derivatives, which recognizes an unpaired guanine base and are good probes for fluorescent indicator displacement (FID) assays, respectively.

Model-based analysis of multi-UAV path planning for surveying postdisaster building damage.

Emergency responders require accurate and comprehensive data to make informed decisions. Moreover, the data should be acquired and analyzed swiftly to ensure an efficient response. One of the tasks at hand post-disaster is damage assessment within the impacted areas.
