Integrin regulation of caveolin function
Caveolae are unique organelles that are found in the plasma membrane of many cell types. They participate in various processes such as lipid recycling, cellular signalling and endocytosis. A variety of signalling molecules localize to caveolae in response to various stimuli, providing a potential mechanism for the spatial regulation of signal transduction pathways. Caveolin-1, a constitutive pr...
متن کاملMena binds α5 integrin directly and modulates α5β1 function
Mena is an Ena/VASP family actin regulator with roles in cell migration, chemotaxis, cell-cell adhesion, tumor cell invasion, and metastasis. Although enriched in focal adhesions, Mena has no established function within these structures. We find that Mena forms an adhesion-regulated complex with α5β1 integrin, a fibronectin receptor involved in cell adhesion, motility, fibronectin fibrillogenes...
متن کاملThe mechanical integrin cycle.
Cells govern tissue shape by exerting highly regulated forces at sites of matrix adhesion. As the major force-bearing adhesion-receptor protein, integrins have a central role in how cells sense and respond to the mechanics of their surroundings. Recent studies have shown that a key aspect of mechanotransduction is the cycle by which integrins bind to the matrix at the leading cell edge, attach ...
متن کاملThrombospondin Modulates OLv~ 3 Function through Integrin-associated Protein
Integrin-associated protein (IAP) is a receptor for the carboxyl-terminal "cell-binding domain" (CBD) of thrombospondin 1 (TS1). lAP associates with av[33 integrin and mAbs against lAP inhibit certain integrin functions. Here we examine the effects of the TS1 CBD and 4N1K (KRFYVVMWKK), a cell-binding peptide derived from it, on the adhesion and spreading on vitronectin (VN) of C32 human melanom...
متن کاملMutation in the CD45 inhibitory wedge modulates integrin activation and leukocyte recruitment during inflammation.
Neutrophil recruitment to the site of inflammation plays a pivotal role in host defense. Src family kinases (SFKs) activation is required for integrin and chemokine signaling as well as immune cell function. The receptor-like protein tyrosine phosphatase CD45 positively regulates chemoattractant signaling acting on SFK activity. To further investigate the role of CD45 in neutrophil recruitment ...
