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 two elements: a cis-repressive sequence upstream of RBS in mRNA, and a ncRNA 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. Trans-activating RNA can form complementary bases to cis-repressive sequence and expose the RBS for ribosomal binding, allowing translation to occur.

RNA Aptamer

A RNA aptamer is any RNA molecule that can fold into a tertiary confirmation that binds with strong affinity and high specificity to small molecules through non-Watson-Crick base pairing.

Designer Part Number Description

Single-guide RNA (sgRNA)

sgRNAs work in the CRISPR/Cas system. They are constructed by fusing functional domains of CRISPR RNA (crRNA) and trans-acting crRNA (tracrRNA) together through RNA linkers. They associate with Cas proteins or their derivatives and guide them to DNA with complementarity with the targeting sequence of crRNA.

Designer Part Number Description


RNA-OUT is a small ncRNA that works at the RNA level. RNA-OUT will bind to 5'UTR, which include the RBS of mRNA and prevents the ribosome from binding to mRNA to inhibit translation of downstream gene. RNA-IN is also a ncRNA 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 initiating translation.

Designer Part Number Description

RNA interference (RNAi)

: Small interfering RNAs (siRNAs) and micro RNAs (miRNAs) work in the RNA interference (RNAi) pathway. siRNAs are usually produced by "dicing" exogenous, long double stranded RNA into 21-nucleotides small fragments. Whereas miRNAs usually have an endogenous origin and started as hairpin transcripts. They are then processed by Drosha in non-random manner and then by Dicer. siRNAs or miRNAs will then bind to Argonaute in the RNA-induced silencing complex (RISC). The complex then search for RNA targets using the siRNA/miRNA, and in most cases degrades the latter, resulting in inhibition of gene expression.

Designer Part Number Description


A riboswitch is a segment on the mRNA that has the ability to detect small molecules or temperatures, and regulates gene expression in an on or off manner. Riboswitches usually contain sensor domains for binding of small molecules and regulatory domains for gene regulation. Riboswitches are therefore also aptamers in nature. Upon binding of a suitable ligand in the sensor domain, riboswitches undergo conformational changes that can lead to different outcomes like translation inhibition or mRNA degradation.

Designer Part Number Description


A ribozyme is a RNA molecule with intrinsic catalytic activity, usually cleavage and ligation activity

Designer Part Number Description


A RNA aptazyme are RNAs that carry properties from both aptamer and ribozyme. It is capable of sensing small molecules. Upon activation by a ligand, it can trigger ribozyme-mediated cleavage.

The aptamer and ribozyme domain MUST be Functionally related to be categorize as aptazyme, linkage of aptamer and ribozyme alone which results in no functional relation MUST be regarded as a composite device with aptamer and ribozyme only.

Designer Part Number Description


pT181 is a special class of ncRNAs derived from elements in Staphylococcus aureus pathogenicity plasmid pT181. A specific 5’ UTR region would normally form an anti-termination loop. Upon interacting with a pT181-RNAi, a premature terminator loop 5’ to the CDS will form and result in early termination before the mRNA can be completely transcribed.

Designer Part Number Description


This category contains ncRNA with dual or more functions resulting from combining 2 or multiple natures / functions of existing ncRNAs.
