The ER forms a contiguous structure of interconnected sheets and tubules that
spreads from the nuclear envelope to the cell cortex. Through its attachment to
the cytoskeleton, the ER undergoes dynamic rearrangements, such as tubule
extension and movement. ER shaping proteins (reticulons and DP1/Yop1p) play key
roles in generating and maintaining the unique reticular morphology of the ER.
Atlastin and its yeast homologue, Sey1p, mediate homotypic ER membrane fusion,
which leads to the formation of new three-way junctions within the polygonal
network. At these junctions, the Lunapark protein, Lnp1p, works in conjunction
with the reticulons, DP1/Yop1p, and in antagonism to atlastin/Sey1p to maintain
the network in a dynamic equilibrium. Defects in ER morphology have been linked
to certain neurological disorders.
