TANGO1 has an uncommon membrane helix organisation, composed of one membrane-spanning helix and one other that penetrates the inner leaflet . We have reconstituted these membrane helices in model membranes and proven that TM and IM together reduce the circulate of lipids at a region of outlined form. We have also shown that the helices align TANGO1 around an ER exit web site.

Here they use excessive-decision imaging and deletion mutagenesis to further characterize lateral interactions that stabilize the rings, together with a potential role for the not-too-nicely-characterized NRZ tethering advanced. They also use modeling to generate a theoretical part diagram for ring formation and fusion (my first encounter with the word 'lineactant', which based on a little bit of Googling is rather obscure). This could have made sense in mild of the physical model, but now it appears a bit odd to be included in the text. Our data is all in regards to the assembly of a ring of TANGO1 at the neck for the newly forming collagen-containing carriers. Whether it grows and is launched within the form of a mega service or, for example, fuses on to the Golgi cannot be stated at all.

But, we now included in Figure eight what we suggest is the following step in the growth of the container as a big tubule where the tip is uncoated and the based mostly containing the coats is captured by TANGO1. Yes, we would like to do that and we try to persuade Wolfgang Baumeister to help visualise this arrangement of TANGO1 by cryo-electron microscopy. We have depleted solely Sec23A, which would depart Sec23B, and therefore try and restrict mobile endomembrane stress. There is just no other method to address the involvement of COPII without decreasing their ranges. But based on this concern, we have now included an announcement in the text to frame our findings with this caveat.

We counsel this can be a mechanism to stop membrane mixing during TANGO1-mediated transfer of bulky secretory cargos from the ER to the ERGIC/Golgi via a tunnel.

Unfortunately, we can not include the outline of cells, as we did not purchase a part contrast picture at the time. One of us additionally needed to spend appreciable time in attempting to grasp the principle of lineactant. But, as talked about above, our biophysicists pals began the evaluation of our data by summarizing it as a lineactant. The authors continue their quest to know how giant cargoes are accommodated in COPII vesicles. In a recent JCB paper, they reported that TANGO1, known to be important for collagen export from the ER, assembles into rings around COPII coats at ER exit sites.
