A cross section of an area of sheets (left) and tubules (right) is shown
to illustrate the localization of the 6 known mammalian ER membrane ER-phagy
receptors. RTN3L localizes to tubules, ATL3 is present at the three-way
junctions of the ER tubules, and FAM134B resides on the curved edges of the
sheets. The other receptors, i.e., SEC62, CCPG1 and TEX264, are found on flat ER
sheets and tubules. Figure created in Biorender.
