Retrograde Transport Pathway

Retrograde Transport Pathway. DyneinSNAPINmediated retrograde transport plays a key role in the The toxin undergoes retrograde vesicular transport from the TGN, via the Golgi cisternae, to the ER before the catalytic A fragment crosses a membrane Initially, it was considered that mammalian retromer functions in the equivalent retrograde transport pathway, as demonstrated by retromer dependency of retrograde transport of cation-independent.

This pathway may be very inefficient, but the extreme potency of these toxins ensures that a lethal amount enters the cytosol. Retrograde traffic from the cis-Golgi to the ERGIC or the ER occurs through either COPI-coated vesicles or through a less well characterized RAB6-dependent route that makes use of tubular carriers (reviewed in Lord et al, 2013; Spang et al, 2013; Heffernan and Simpson, 2014).

Retrograde transport of growth-inhibitory signals may be part of the normal neuronal maturation pathway during development This pathway may be very inefficient, but the extreme potency of these toxins ensures that a lethal amount enters the cytosol.

A model for vesiclemediated anterograde/retrograde protein transport. The anterograde pathway, from the endoplasmic reticulum through the trans-Golgi network to the cell surface, is utilized by trans-membrane and secretory proteins.The retrograde pathway, which directs traffic in the opposite direction, is used following endocytosis of exogenous molecules and recycling of membrane proteins. Retrograde transport is shown starting from a coated endosome, which is an intermediate in the maturation between early and late endosomes 27,28.The coated endosome is connected to a vast 'tubular.
