This part codes for the <b>yellow fluorescent protein</b> with the poetic name <b>mVenus</b>.<ref><b>Gert-Jan Kremers</b>, Joachim Goedhart, Erik B. van Munster, and Theodorus W. J. Gadella. Cyan and Yellow Super Fluorescent Proteins with Improved Brightness, Protein Folding, and FRET Förster Radius, Biochemistry 2006 45 (21), 6570-6580, DOI: 10.1021/bi0516273</ref> It is a deviation of the famous green fluorescent protein <b>GFP</b> originally isolated from the <b>bioluminescent jellyfish</b> <i>Aequorea victoria</i> in 1962.<ref><b>Shimomura, O.</b>, Johnson, F.H. and Saiga, Y. (1962) Extraction, Purification, and Properties of Aequorin, a Bioluminescent Protein from the Luminous Hydromedusan, Aequorea.

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 <b>fluorescence spectroscopy</b> and <b>microscopy</b>.<ref><b>M.A. Rizzo</b>, D.W. Piston

<h1>Data</h1>

We were able to <b>successfully clone</b> this basic part into its respective L0 plasmid backbone and to <b>confirm</b> the integrity of the L0 construct via <b>restriction digest</b> and gel electrophoresis, see <i>Figure 1</i>. Furthermore, we were able to include it into a <b>L1 construct</b>, proving its correct adaptation towards MoClo assembly, see <i>Figure 2</i>. This part has been transfected into Leishmania, but it has <b>not yet</b> been tested for expression and functionality after purification.

<h1>The MocloMania collection</h1>
<p>This basic part is part of the <b>MocloMania collection</b>, the very first collection of genetic parts specifically designed and optimized for Modular Cloning assembly and recombinant protein expression in the protozoan parasite <i>Leishmania tarentolae</i>.</p>
<p>Are you trying to express <b>complexly glycosylated proteins</b>? Large antibody side chains? Human proteins that require <b>accurate post-translational modification</b>? Then Leishmania might be just the right organism for you! <i>Leishmania tarentolae</i>’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 <b>easy transfection</b> and <b>cultivation</b>.</html><ref><b>Langer T</b>, Corvey C, Kroll K, Boscheinen O, Wendrich T, Dittrich W. Expression and purification of the extracellular domains of human glycoprotein VI (GPVI) and the receptor for advanced glycation end products (RAGE) from Rattus norvegicus in Leishmania tarentolae. Prep Biochem Biotechnol. 2017 Nov 26;47(10):1008-1015. doi: 10.1080/10826068.2017.1365252. Epub 2017 Aug 31. PMID: 28857681.</ref><html> So instead of relying on mammalian cell lines,  try considering Leishmania as your new expression host of choice!</p>
<p>Our MocloMania collection will allow you to easily modify your protein of choice and make it suitable for downstream <b>detection</b> and <b>purification procedures</b> - all thanks to the help of <b>Modular Cloning</b>. This cloning system was first established by <b>Weber et al.</b> in <b>2011</b> and relies on the ability of <b>type IIS restriction enzymes</b> to cut DNA outside of their recognition sequence, hereby generating four nucleotide overhangs.</html><ref><b>Weber E</b>, Engler C, Gruetzner R, Werner S, Marillonnet S (2011) A Modular Cloning System for Standardized Assembly of Multigene Constructs. PLoS ONE 6(2): e16765. https://doi.org/10.1371/journal.pone.0016765</ref><html> Every basic part in our collection is equipped with a <b>specified set of overhangs</b> that assign it to its designated position within the reading frame. These so-called <b>cloning positions</b> are labelled <b>B2-B5</b> 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 <b>fusion protein</b> of your desire.</p>
<p>We furthermore provide a specifically domesticated <b>Leishmania expression vector</b>, named <a href="https://parts.igem.org/Part:BBa_K3781105"><b>weird_plex</b></a>, which will package your fusion construct into a functional <b>transcriptional unit</b> that is optimized for high expression in Leishmania.
<p>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 <b>simultaneously</b> in a simple <b>one-step</b>, <b>one-pot reaction</b>. This will safe you a lot of time and frustration in your cloning endeavours!</p>
<p>Do we have your attention? In the <b>table below</b> 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 <a href="https://2021.igem.org/Team:TU_Kaiserslautern/Description">Leishmania and Modular Cloning</a> as well as to understand how this basic part integrates into our <a href="https://2021.igem.org/Team:TU_Kaiserslautern/Part_Collection"><b>part collection</b></a>. See you there!</p>
