  • To exemplify the accessibility of the method, we characterized the oligomerization of GFP-tagged myotubularin induced by hypo-osmotic treatment at the ultrastructural level.

  • We provide examples of the dynamic oligomerization of GFP-tagged myotubularin (MTM1) phosphoinositides phosphatase induced by osmotic stress, and of the ultrastructure of membrane tubules dependent on amphiphysin 2 (BIN1) expression.

  • Some PTP members of the PTEN and myotubularin families have evolved to dephosphorylate phosphatidylinositol phosphates specifically

    PLoS ONE Alerts: New Articles

  • The second PTP domain (D2) of many classical receptor-like PTPs and the PTP domain of dual-specificity pseudophosphatases of the myotubularin family lack critical residues essential for their catalytic activity

    PLoS ONE Alerts: New Articles

  • This nucleation is enhanced by the GFP tag, as untagged proteins usually retain normal localization, and is dependent on the myotubularin sequence as the localization of close homologues is not similarly affected (
