Robertsonian translocation, a chromosomal rearrangement in pairs 13, 14, 15, 21, and 22; Nonreciprocal translocation, transfer of genes from one chromosome to another; PEP group translocation, a method used by bacteria for sugar uptake; Twin-arginine translocation pathway, a protein export pathway found in plants, bacteria, and archaea
ANT has long been thought to function as a homodimer, but this concept was challenged by the projection structure of the yeast Aac3p solved by electron crystallography, which showed that the protein was three-fold symmetric and monomeric, with the translocation pathway for the substrate through the centre.

The twin-arginine translocation pathway (Tat pathway) is a protein export, or secretion pathway found in plants, bacteria, and archaea.In contrast to the Sec pathway which transports proteins in an unfolded manner, the Tat pathway serves to actively translocate folded proteins across a lipid membrane bilayer.
In the activation pathway illustrated to the left, the ligand involved is a cytokine and the specific kinase taking part in activation is JAK.The dimerized STAT5 represents the active form of the protein, which is ready for translocation into the nucleus.
The translocon (also known as a translocator or translocation channel) is a complex of proteins associated with the translocation of polypeptides across membranes. [1] In eukaryotes the term translocon most commonly refers to the complex that transports nascent polypeptides with a targeting signal sequence into the interior (cisternal or lumenal) space of the endoplasmic reticulum (ER) from ...
The structures of BtuCD and the BtuCD homolog, HI1470/1, represent two different conformational states of an ABC transporter. The predicted translocation pathway in BtuCD is open to the periplasm and closed at the cytoplasmic side of the membrane while that of HI1470/1 faces the opposite direction and open only to the cytoplasm.
The twin-arginine translocation pathway (Tat pathway) is similar to Sec in the process of protein secretion, however, it sends proteins only in their folded (tertiary) state. It is used by all types of bacteria, as well as archaea, and chloroplasts and mitochondria of plants. [ 12 ]
PEP (phosphoenol pyruvate) group translocation, also known as the phosphotransferase system or PTS, is a distinct method used by bacteria for sugar uptake where the source of energy is from phosphoenolpyruvate (PEP). It is known to be a multicomponent system that always involves enzymes of the plasma membrane and those in the cytoplasm.
