== Publication Abstract from PubMed == | |||
The interaction between ubiquitinated proteins and intracellular proteins harboring ubiquitin binding domains (UBDs) is critical to a multitude of cellular processes. Here, we report that Rabex-5, a guanine nucleotide exchange factor for Rab5, binds to Ub through two independent UBDs. These UBDs determine a number of properties of Rabex-5, including its coupled monoubiquitination and interaction in vivo with ubiquitinated EGFRs. Structural and biochemical characterization of the UBDs of Rabex-5 revealed that one of them (MIU, motif interacting with ubiquitin) binds to Ub with modes superimposable to those of the UIM (ubiquitin-interacting motif):Ub interaction, although in the opposite orientation. The other UBD, RUZ (Rabex-5 ubiquitin binding zinc finger) binds to a surface of Ub centered on Asp58(Ub) and distinct from the "canonical" Ile44(Ub)-based surface. The two binding surfaces allow Ub to interact simultaneously with different UBDs, thus opening new perspectives in Ub-mediated signaling. | |||
