Publication Abstract from PubMed
Mad2 participates in spindle checkpoint inhibition of APC(Cdc20). We show that RNAi-mediated suppression of Mad1 function in mammalian cells causes loss of Mad2 kinetochore localization and impairment of the spindle checkpoint. Mad1 and Cdc20 contain Mad2 binding motifs that share a common consensus. We have identified a class of Mad2 binding peptides with a similar consensus. Binding of one of these ligands, MBP1, triggers an extensive rearrangement of the tertiary structure of Mad2. Mad2 also undergoes a similar striking structural change upon binding to a Mad1 or Cdc20 binding motif peptide. Our data suggest that, upon checkpoint activation, Mad1 recruits Mad2 to unattached kinetochores and may promote binding of Mad2 to Cdc20.
The Mad2 spindle checkpoint protein undergoes similar major conformational changes upon binding to either Mad1 or Cdc20.,Luo X, Tang Z, Rizo J, Yu H Mol Cell. 2002 Jan;9(1):59-71. PMID:11804586[1]
