    ..1G are distributed underneath the plasma membrane in PC12 cells. Collectively, these observations suggest that brain 4.1R and 4.1G may modulate the membrane mechanical properties of neuronal cells by promoting fodrin/actin association. ..

    ..Biol. Chem. 282, 2029-2037 ). Together with the current findings, these data suggest a ankyrin/spectrin-based mechanism for coordinating membrane assembly with extracellular interactions of E-cadherin at sites of cell-cell contact. ..

    ..We conclude that the cortical network involved in the sound-induced electromotility of OHCs contains alphaII-betaV spectrin, and not the conventional alphaII-betaII spectrin. ..

    ..Thus, schwannomin is a tumour suppressor directly involved in actin-cytoskeleton organization, which suggests that alterations in the cytoskeleton are an early event in the pathogenesis of some tumour types. ..

    ..We conclude that variation in the structure of the C-terminal regions of betaII spectrin isoforms correlates with their differential intracellular targeting. ..

    ..Thus, in response to ELF deficiency, the abnormalities of G1/S checkpoint and senescence contribute their increment of susceptibility to malignant transformation. ..
