      Vazquez, Martin P; Mualem, David; Bercovich, Natalia; Stern, Michael Z; Nyambega, Benson; Barda, Omer; Masiga, Dan; Gupta, Sachin K; Michaeli, Shulamit; Levin, Mariano J (Elsevier, 2009-04-01)
      Early in the assembly of the spliceosome of eukaryotes the branch-point binding protein (BBP, also called SF1) recognizes the branch point sequence, whereas the heterodimer U2AF consisting of a 65 and a 35 kDa subunit, ...
    • Protein–protein interaction map of the Trypanosoma cruzi ribosomal P protein complex 

      Ayub, Maximiliano J; Smulski, Cristian R; Nyambega, Benson; Bercovich, Natalia; Masiga, Dan; Vazquez, Martín P; Aguilar, Carlos F; Levin, Mariano J (Elsevier, 2005-09-12)
      The large subunit of the eukaryotic ribosome possesses a long and protruding stalk formed by the ribosomal P proteins. Four out of five ribosomal P proteins of Trypanosoma cruzi, TcP0, TcP1α, TcP2α, and TcP2β had been ...
