The Ankrd 13 family of UIM-bearing proteins regulates EGF receptor endocytosis from the plasma membrane

Ankrd 13A, 13B, and 13D constitute a family of ubiquitin-interacting motif (UIM)-bearing cytoplasmic proteins. They are anchored to the plasma membrane, where they recognize the Lys63-linked polyubiquitin chains tagged to ligand-activated EGF receptor and regulate the endocytosis of EGF receptor from the cell surface in mammalian cells

p120-Catenin Inhibits VE-Cadherin Internalization through a Rho-independent Mechanism

p120-catenin is a cytoplasmic binding partner of cadherins and functions as a set point for cadherin expression by preventing cadherin endocytosis, and degradation. p120 is known to regulate cell motility and invasiveness by inhibiting RhoA activity. However, the relationship between these functions of p120 is not understood. Here, we provide evidence that p120 functions as part of a plasma membrane retention mechanism for VE-cadherin by preventing the recruitment of VE-cadherin into membrane domains enriched in components of the endocytic machinery, including clathrin and the adaptor complex AP-2. The mechanism by which p120 regulates VE-cadherin entry into endocytic compartments is dependent on p120's interaction with the cadherin juxtamembrane domain, but occurs independently of p120's prevention of Rho GTPase activity. These findings clarify the mechanism for p120's function in stabilizing VE-cadherin at the plasma membrane and demonstrate a novel role for p120 in modulating the availability of cadherins for entry into a clathrin-dependent endocytic pathway

Interaction between Epsin/Yap180 Adaptors and the Scaffolds Ede1/Pan1 Is Required for Endocytosis

The spatial and temporal regulation of the interactions among the ∼60 proteins required for endocytosis is under active investigation in many laboratories. We have identified the interaction between monomeric clathrin adaptors and endocytic scaffold proteins as a critical prerequisite for the recruitment and/or spatiotemporal dynamics of endocytic proteins at early and late stages of internalization. Quadruple deletion yeast cells (ΔΔΔΔ) lacking four putative adaptors, Ent1/2 and Yap1801/2 (homologues of epsin and AP180/CALM proteins), with a plasmid encoding Ent1 or Yap1802 mutants, have defects in endocytosis and growth at 37°C. Live-cell imaging revealed that the dynamics of the early- and late-acting scaffold proteins Ede1 and Pan1, respectively, depend upon adaptor interactions mediated by adaptor asparagine-proline-phenylalanine motifs binding to scaffold Eps15 homology domains. These results suggest that adaptor/scaffold interactions regulate transitions from early to late events and that clathrin adaptor/scaffold protein interaction is essential for clathrin-mediated endocytosis
