mCh

Codon optimized mCherry red fluorescent protein

Usage and Biology

The mushroom coral Discosoma sp. is the source of monomeric RFP.

mCherry is a mutant derivative of mRFP. PDB 2H5Q is shown here. N = amino terminus; C = carboxyl terminus.

• Protein Data Bank ID 2H5Q

"Monomeric cherry" (mCherry) red fluorescent protein is a derivative of monomeric RFP from the mushroom coral Discosoma sp. (Shaner et al. 2004, Shu et al. 2006). This BioBrick was codon optimized (by the lab of Pam Silver) for expression in human/ mammalian cells. Only a single copy is needed for detectable signal. We have assembled two copies in tandem to create a "bulky" protein for use as an artificial transcriptional repressor (Haynes et al. 2012).
