    • Cooperativity in proton sensing by PIP aquaporins 

      Vitali, Victoria Andrea; Jozefkowicz, Cintia; Canessa Fortuna, Agustina; Soto, Gabriela Cinthia; Gonzalez Flecha, Francisco Luis; Alleva, Karina Edith (Wiley, 2019-03)
      One of the most intriguing properties of plasma membrane intrinsic protein (PIP) aquaporins (AQPs) is their ability to modulate water transport by sensing different levels of intracellular pH through the assembly of homo‐ ...

    • Free cholesterol and cholesterol esters in bovine oocytes: Implications in survival and membrane raft organization after cryopreservation 

      Buschiazzo, Jorgelina; Rios, Glenda Laura; Canizo, Jésica Romina; Antollini, Silvia Susana; Alberio, Ricardo (2017)
      Part of the damage caused by cryopreservation of mammalian oocytes occurs at the plasma membrane. The addition of cholesterol to cell membranes as a strategy to make it more tolerant to cryopreservation has been little ...

    • PIP aquaporin pH sensing is regulated by the length and charge of the C-terminal region 

      Scochera, Florencia; Zerbetto De Palma, Gerardo; Canessa Fortuna, Agustina; Chevriau, Jonathan; Toriano, Roxana; Soto, Gabriela Cynthia; Zeida, Ari; Alleva, Karina Edith (Wiley, 2021-07)
      Plant PIP aquaporins play a central role in controlling plant water status. The current structural model for PIP pH-gating states that the main pH sensor is located in loopD and that all the mobile cytosolic elements ...

    • Pip water transport and its pH dependence are regulated by tetramer stoichiometry 

      Jozefkowicz, Cintia; Sigaut, Lorena; Scochera, Florencia; Soto, Gabriela Cinthia; Ayub, Nicolás Daniel; Pietrasanta, Lía Isabel; Amodeo, Gabriela; Gonzalez Flecha, Francisco Luis; Alleva, Karina Edith (2016)
      Many plasma membrane channels form oligomeric assemblies, and heterooligomerization has been described as a distinctive feature of some protein families. In the particular case of plant plasma membrane aquaporins (PIPs), ...

    • Seminal plasma proteins interacting with sperm surface revert capacitation indicators in frozen-thawed ram sperm 

      Ledesma, Alba; Fernández Alegre, Estela; Cano, Adriana Virginia; Hozbor, Federico Andres; Martínez Pastor, Felipe; Cesari, Andreina (Elsevier, 2016-10)
      This study was conducted to evaluate the effects of interacting seminal plasma proteins (iSPP) obtained by AV or EE on frozen-thawed ram sperm in order to test the hypothesis whether this fraction could be sufficient to ...
