Method and composition for crystallizing G protein-coupled receptors |
摘要 |
Certain embodiments provide a method for crystallizing a GPCR. The method may employ a fusion protein comprising: a) a first portion of a G-protein coupled receptor (GPCR), where the first portion comprises the TM1, TM2, TM3, TM4 and TM5 regions of the GPCR; b) a stable, folded protein insertion; and c) a second portion of the GPCR, where the second portion comprises the TM6 and TM7 regions of the GPCR. |

1. A fusion protein comprising, from N-terminus to C-terminus:
a) a first portion of a G-protein coupled receptor (GPCR), wherein said first portion comprises TM1, TM2, TM3, TM4 and TM5 regions of said GPCR; b) a heterologous domain comprising an amino acid sequence that is at least 80% identical to the amino acid sequence of a soluble, autonomously folding, wild-type protein that aids in the formation of lattice contacts during crystallization of the fusion protein; c) a second portion of said GPCR, wherein said second portion comprises TM6 and TM7 regions of said GPCR. |
