mVenus Fused to Mouse Myosin Light Chain
Named for the brightest object in the nighttime sky, Venus is a high-performance yellow-emitting Aequorea victoria GFP derivative. Venus has peak excitation and emission wavelengths of 515 and 528, respectively, and is only about 25 percent as photostable as EGFP. The expression of the monomeric form of Venus fused to myosin light chain is demonstrated in the digital image above. Although they were once thought to be present only in muscle cells, myosins reside in almost all eukaryotic cells, where they move along actin filaments while hydrolyzing ATP.
