## Abstract

SUMMARY
We are analyzing, annotating, organizing, and integrating nucleic acid 3D structural data with sequence and
functional data and delivering it to biomedical researchers. The significance of the proposal lies in the prominent
roles of nucleic acids in a host of cellular and physiological processes, mediated by interaction with specific DNA-
and RNA-binding proteins. DNA encodes genetic information and takes part in replication, recombination,
transcription, and repair. RNA transmits genetic information and takes part in all aspects of gene regulation. RNA
is also the key component of the ribosome, the universal protein-making nano-machine and an important target
for drug design. RNA/DNA hybrids occur in many biological contexts, including transcription complexes, origins
of replication, and the widely heralded CRISPR-CAS systems for precision editing of genes (Wright 2016). They
form unique structures different from double helical RNA or DNA. High throughput methods have catalogued
many new non-coding RNAs (ncRNAs) and RNA-binding proteins lacking previously known RNA-binding
domains. The Specific Aims of this proposal are: 1) Create more complete annotations for all nucleic acid 3D
structures, 2) create new annotations for nucleic acid-protein complexes, and 3) create a Nucleic Acid
Knowledge Base (NAKB) that allows for both deep and wide searching of information about nucleic acid
sequences and structures. Under these aims, we will analyze and annotate all types of nucleic acid 3D structures,
including DNA, RNA, and DNA/RNA hybrids, and improve our ability to predict 3D structures from sequence.
The NAKB resource will provide new search capabilities, enhanced reports, and link-outs to external data,
features and tools. The proposed enhancements will greatly improve our abilities to search and visualize existing
data on nucleic acid sequence and structural features and will further enrich the user experience and enable
data discovery. The innovation of the proposal is the creation of a unified resource for all nucleic acid 3D
structures.
