Possible roles of the endocytic cycle in cell motility [PDF]
Journal of Cell Science, 2007 Starving, highly motile Dictyostelium cells maintain an active endocytic cycle, taking up their surface about every 11 minutes. Cell motility depends on a functional NSF (N-ethylmaleimide sensitive factor) protein - also essential for endocytosis and membrane trafficking generally - and we, therefore, investigated possible ways in which the endocytic ...

Iron uptake from transferrin and transferrin endocytic cycle in friend erythroleukemia cells
Journal of Cellular Physiology, 1987 AbstractSeveral aspects of iron metabolism were studied in cultured Friend erythroleukemia cells before and after induction of hemoglobin synthesis by dimethyl sulfoxide. The maximal rate of iron uptake from 59Fe‐labeled transferrin, 1.5 × 106 atoms of Fe/cell per 30 min in uninduced cells, increased to 3 × 106 atoms/cell after 5 days of induction. The

Optimal control of receptor reinsertion in the Low Density Lipoprotein endocytic cycle [PDF]
Mathematical Biosciences, 1999 On the basis of this study, it is concluded that within physiological limits the minimum value for the mean capture time of LDL receptors by coated pits must be induced fundamentally by an optimal characterization of their insertion rate function. The corresponding steady-state surface aggregation patterns for the unbound receptors are consistent with ...

The synapsin cycle: A view from the synaptic endocytic zone
Journal of Neuroscience Research, 2007 AbstractAlthough the synapsin phosphoproteins were discovered more than 30 years ago and are known to play important roles in neurotransmitter release and synaptogenesis, a complete picture of their functions within the nerve terminal is lacking. It has been shown that these proteins play an important role in the clustering of synaptic vesicles (SVs ...

Dynamics of the orphan myosin MyoF over Trypanosoma cruzi life cycle and along the endocytic pathway
Parasitology International, 2021 Trypanosoma cruzi proliferative forms perform endocytosis through a specialized structure named the cytostome-cytopharynx complex (SPC). The SPC is a specialized invagination of the cell membrane that extends through the cell body towards the posterior regions, with its aperture close to the flagellar pocket. Recently, diverse proteins were found along

A Whole Cell Kinetic Model of the Endocytic Cycle: Focus on Sorting
, 1989 In Chapters 3 and 4, equilibrium and kinetic schemes were examined in order to elucidate the mechanism by which receptors and ligands are sorted in the endosome. The most successful of these mechanisms, in terms of explaining the efficient recycling of receptors from the endosome back to the cell surface, suggested that receptors diffuse from the ...

Synaptic vesicles retain their identity through the endocytic cycle
Nature, 1998 After fusion of synaptic vesicles with presynaptic membrane and secretion of the contents of the vesicles into the synaptic cleft (a process known as exocytosis), the vesicular membrane is retrieved by endocytosis (internalization) for re-use. Several issues regarding endocytosis at central synapses are unresolved, including the location of membrane ...
