Figure 3: Import of matrix proteins into peroxisomes. Cargo-loaded PTS1 and PTS2 receptors dock to the cytosolic surface of the peroxisomal membrane to initiate the cascade of peroxin-mediated ...

This latter targeting system makes use of cpSRP54 together with a distinct cpSRP43 protein, but lacks the conserved SRP RNA of the bacterial and cytosolic SRPs. So how does the cpSRP work without ...
