Literature

New insights into the molecular mechanism of the Rab GTPase Sec4p activation.

  • PubMed Abstract: 
  • Sec4p is a small monomeric Ras-related GTP-binding protein (23 kDa) that regulates polarized exocytosis in S. cerevisiae. In this study we examine the structural effects of a conserved serine residue in the P-loop corresponding to G12 in Ras.
