mVenus, MoCloMania B3_B4
This part codes for the yellow fluorescent protein with the poetic name mVenus.[1] It is a deviation of the famous green fluorescent protein GFP originally isolated from the bioluminescent jellyfish Aequorea victoria in 1962.[2] By coupling a protein of interest with a fluorescent tag such as mVenus, the target protein can be easily and non-invasively detected within living cells as well as cell preparations with the help of fluorescence spectroscopy and microscopy.[3]
size 26.9 kDa
function fluorescent tag
excitation wavelength 515 nm
emission wavelength 537 nm
cloning position B3_B4
plasmid backbone pAGM1287
Data
We were able to successfully clone this basic part into its respective L0 plasmid backbone and to confirm the integrity of the L0 construct via restriction digest and gel electrophoresis, see Figure 1. This part has not yet been introduced into a L1 construct and thus has not yet been transfected into Leishmania to test expression and functionality. We are working hard on realizing these experiments in order to qualitatively validate the functionality of our basic part.

The MocloMania collection
This basic part is part of the MocloMania collection, the very first collection of genetic parts specifically designed and optimized for Modular Cloning assembly and recombinant protein expression in the protozoan parasite Leishmania tarentolae.
Are you trying to express complexly glycosylated proteins? Large antibody side chains? Human proteins that require accurate post-translational modification? Then Leishmania might be just the right organism for you! Leishmania tarentolae’s glycosylation patterns resemble those of human cells more closely than any other microbial expression host, while still delivering all the benefits of microbial production systems like easy transfection and cultivation.[4] So instead of relying on mammalian cell lines, try considering Leishmania as your new expression host of choice!
Our MocloMania collection will allow you to easily modify your protein of choice and make it suitable for downstream detection and purification procedures - all thanks to the help of Modular Cloning. This cloning system was first established by Weber et al. in 2011 and relies on the ability of type IIS restriction enzymes to cut DNA outside of their recognition sequence, hereby generating four nucleotide overhangs.[5] Every basic part in our collection is equipped with a specified set of overhangs that assign it to its designated position within the reading frame. These so-called cloning positions are labelled B2-B5 from upstream to downstream. By filling all positions with the basic parts of your choice, you can easily generate variable genetic constructs that code for the fusion protein of your desire.
We furthermore provide a specifically domesticated Leishmania expression vector, named weird_plex, which will package your fusion construct into a functional transcriptional unit that is optimized for high expression in Leishmania.
The best part? Because of the type IIS restriction properties and the specifity of the generated overhangs, restriction and ligation of your construct can all happen simultaneously in a simple one-step, one-pot reaction. This will safe you a lot of time and frustration in your cloning endeavours!
Do we have your attention? In the table below you can find some basic information on how our cloning system, along with most other MoClo systems, is set up. Please feel free to check out our wiki to find more information on Leishmania and Modular Cloning as well as to understand how this basic part integrates into our part collection. See you there!
