Abstract:
Cell-penetrating peptides (CPP), also called protein transduction domains (PTD), membrane-permeable peptides (MPP), or Trojan horse peptides, have been used in many different research areas. The delivery of heat shock proteins (Hsp) using CPP has been applied in models for apoptosis, necrosis, oxidative stress, neurodegenerative diseases, stroke, cystic fibrosis, smooth muscle relaxation, myocardial injury, scar formation, and others. This review summarizes the accomplishments of the field over the last years and discusses why Hsp are particularly suitable for CPP-mediated delivery.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
