The N-terminal RTPmu signal sequence is cleaved during expression. The C-terminal AVI-HIS tag was cleaved by caspase-3 after the DEVD site. In reference to the native sequence, the final protein sequence starts at Q63 and ends at G194, as it lacks an N-terminal region from T31 to K62. Source: (gene. exp.) ![]() ![]() ![]() ![]() | ||||
