Like most G-protein coupled receptors, hGPR40 contains <scene name='72/721541/Top_view_transmembrane_helices/2'>seven transmembrane helices</scene> (<scene name='72/721541/Top_view_transmembrane_helices/1'>top view of TM helices</scene>). To obtain a crystallized structure of the protein, four <scene name='72/721541/Stabilizing_mutations/4'>stabilizing mutations</scene> (<scene name='72/721541/L42a/ | Like most G-protein coupled receptors, hGPR40 contains <scene name='72/721541/Top_view_transmembrane_helices/2'>seven transmembrane helices</scene> (<scene name='72/721541/Top_view_transmembrane_helices/1'>top view of TM helices</scene>).

These mutations did not significantly impact the enzyme's binding affinity with a known agonist, TAK-875. A <scene name='72/721541/Lysozyme_crimson/2'>T4 Lysozyme</scene> (shown in <FONT COLOR="#DC143C">crimson</FONT>) was also added to intracellular loop 3 to aid in the formation of crystals. The lysozyme also had little effect on TAK-875 binding.<ref name="Srivastava"/> For clarity, the lysozyme is removed in all further renderings of hGPR40. | ||
