  • PubMed Abstract: 

    The ErbB-3 receptor binding protein (Ebp1) is a member of the proliferation-associated 2G4 (PA2G4) family implicated in regulation of cell growth and differentiation. Here, we report the crystal structure of the human Ebp1 at 1.6 A resolution. The protein has the conserved pita bread fold of methionine aminopeptidases, but without the characteristic enzymatic activity. Moreover, Ebp1 is known to interact with a number of proteins and RNAs involved in either transcription regulation or translation control. The structure provides insights in how Ebp1 discriminates between its different interaction partners.
