exocytosis and the remodeling
of the cell's internal skeleton, but what that connection is remains unclear.
This regulation is spectacularly apparent in the exquisite speed and precision
of synaptic
exocytosis, where synaptotagmin (the calcium - ion sensor for fusion) cooperates with complexin (the clamp activator) to control the precisely timed release
of neurotransmitters that initiates synaptic transmission and underlies brain function.

of LAMP -1-mediated lysosomal
exocytosis by neutrophils in the bone marrow cavity.

We further demonstrate that lysosomal
exocytosis mediates the resealing
of primary skin fibroblasts wounded during the contraction
of collagen matrices.
[MR: This is because lack
of Neu1 means that it's not available to strip sialic acids from LAMP - 1, and oversialylated LAMP - 1 leads to loss
of its inhibitory function over lyso
exocytosis, apparently leading to a nonspecific puking out
of its contents into the ECF].
During an action potential, calcium influx into the presynaptic terminal triggers the fusion
of synaptic vesicles with the plasma membrane, leading to the release

exocytosis.
Rothman came from a different background in cell biology to discover first serendipitously, and then with extensive follow - up work, that the same molecules identified by Scheller and Südhof also regulate the transfer
of material between compartments in cells, as well as secretion by the process
of exocytosis, thus showing the much broader significance
of these proteins to biology in general.
Rothman immediately realised the importance
of the result, and proposed the «SNARE hypothesis» for vesicle transport and
exocytosis as a general process in all cell types: vesicle proteins specifically bind to target proteins in the plasma membrane to form a «v - t» complex which is necessary for vesicle and membrane fusion to proceed.
