AarI B-C part, hM4D

hM4 DREADD flanked by AarI BC sites.

Usage and Biology

This is an engineered version of the human M4 muscarinic receptor that can be activated by the otherwise inert small molecule, clozapine-N-oxide.


Characterization by Team UCSF 2010

In 2009 we used this synthetic GPCR to mediate chemotaxis towards the ligand, CNO.
For more information, refer to our wiki here: http://2009.igem.org/Team:UCSF

In 2010, we showed that this synthetic GPCR increases killer cell activation in the presence of the ligand, CNO:

A synthetic GPCR shown to mediate immune cell migration towards the ligand CNO was introduced to T cells as a potential way to increase the level of kinase activation. IL-2 production was used as a measure of T-cell activation. The results show that in the presence of CNO, T cells transfected with the synthetic GPCR have a higher level of activation than non-transfected T-cells.
