mEmerald Fused to Human Myotilin
Through the ongoing engineering of EGFP, several green variants with improved characteristics have been developed. One of the best of these variants is Emerald, which was named for the precious gemstone that shares its coloring. Emerald exhibits both improved photostability and brightness compared to EGFP. In the digital image above, mEmerald (the monomeric form of Emerald) is shown fused to human myotilin, which induces the formation of actin bundles in non-muscle cells. In localization, myotilin appears to congregate in regions containing myosins and alpha-actinin.
