Signal sequence region of mitochondrial precursor proteins binds to mitochondrial import receptor.

abstract：:Bacteriophytochromes sense light in the near-infrared window, the spectral region where absorption by mammalian tissues is minimal, and their chromophore, biliverdin IXα, is naturally present in animal cells. These properties make bacteriophytochromes particularly attractive for optogenetic applications. However, the ...
