Integrin recycle
Nettet18. jan. 2024 · Integrins that are exposed on the cell surface connect the intracellular actin network to the extracellular matrix ( Vicente-Manzanares et al., 2009 ). Integrin levels at the cell surface are controlled both by their endocytosis into endosomes and their subsequent recycling back to the plasma membrane ( Moreno-Layseca et al., 2024 ). Nettet11. mar. 2010 · Biochemical Integrin β1 Recycling Assay Antibody binding, integrin internalization, and integrin recycling were performed as described above except for fixation of the samples. Instead, recycled integrin antibodies at the surface were removed by a second acid wash after 0 and 5 min of recycling.

For cells adherent to fibronectin, differential engagement of α5β1 and αVβ3 integrins is used to elicit changes in adhesion complex stability, mechanosensation, matrix assembly, and migration, but the …
Nettet30. mar. 2024 · It is known that active and inactive integrin conformers can be recycled through distinct routes. Active and inactive β1 integrins are endocytosed through the same routes to early endosomes [ 21 ]. Then, active β1 is recycled through the long Rab11-dependent recycling loop, whereas the inactive β1 receptor is rapidly recycled … Nettet15. sep. 2006 · The Arf6-dependent recycling of integrins is further regulated by the GTPase-activating protein (GAP) ACAP, which in turn is positively regulated by Akt …
