Catalog for regulatory RNAs

(The page was created as part of iGEM 2014 HKUST team's effort in "Project Riboregulator" to catalog existing regulatory RNAs. Over the years, the number of regulatory RNAs in Part Registry has steadily increased over time and many has been made available to end users. Based on different mode actions and natures of regulatory RNAs, they can be grouped into different categories. However, the Part Registry currently does not have a catalog page, categorizing methods or guidelines to organize and curate existing regulatory RNAs. Some of them are grouped under type "RNA", while others are not. This is not useful for looking up and utilizing them.

We would like to solve this problem by designing a list of category tags as well as a guideline, so that automated display of regulatory RNAs by the <parttable> function can be facilitated. By doing so, we hope that we can assist other users to find and use those parts efficiently.

This page was written in compliance with Part Registry's format for general Catalog Pages. Currently, the information is uploaded manually because we have yet to submit our suggestions to iGEM HQ. Upon approval, we will tag existing regulatory RNAs and complete the page. Being part of the cross-cohort "Project Riboregulator", the page is far from complete and is expected to take shape by Spring 2015. We welcome and encourage constant update and adoption of this page in the future.)


Riboregulators regulate translation by having two elements, a cis-repressive sequence upstream of RBS in mRNA, and a non-coding RNA device, called trans-activating RNA. The cis-repressive sequence will binds to the 5'UTR, including the RBS by Watson-Crick base pairing, the sequestration of RBS represses translation. While trans-activating RNA will form complementary bases to cis-repressive sequence and exposing RBS for ribosomal binding and allow translation.

A riboswitch is a segment on mRNA that have the ability to detect small molecules or temperature, and regulate gene expression in on or off manner. Riboswitches usually contain a region for binding of small molecules, as known as sensor domain, and a region for gene regulation, as known as regulatory domain.In the presence of suitable ligand in the sensor domain, the structure of riboswitch will change. This change in conformation of riboswitch may give various action including translation inhibition or mRNA degradation.

RNA-OUT is a small non-coding RNA that works at RNA level . RNA-OUT will bind to 5'UTR, which include RBS, of mRNA and prevents ribosome from binding to mRNA to inhibit translation of downstream gene. RNA-IN is also a non-coding RNA that is antisense to RNA-OUT and the binding of RNA-IN and RNA-OUT will prevent RNA-OUT from binding to mRNA, thus allowing ribosome to bind to mRNA and initiate translation.

Small interfering RNAs (siRNAs)

siRNAs usually involved in RNA interference pathway. siRNA s are produced by "dicing" long double stranded RNA into 21-nucleotides small fragments. The siRNAs will then bind to a protein and one strand of siRNA is removed. Then siRNA, which have complementary base pairs with its target mRNA, will binds to target mRNA. The binding of siRNA usually causes the degradation of target mRNA, result in inhibition of gene expression.

Single guiding RNA (sgRNAs)

sgRNAs are non-coding RNA that have a hairpin structure mimicking trans-acting RNA and crRNA in CRISPR system. When in complex with Cas9 the,complex are able to target specific DNA sequence and breaking double stranded DNA.
