Structure of a CED-4/CED-9 complexStructure of a CED-4/CED-9 complex

Structural highlights

2a5y is a 3 chain structure with sequence from Caenorhabditis elegans. The September 2014 RCSB PDB Molecule of the Month feature on Apoptosomes by David Goodsell is 10.2210/rcsb_pdb/mom_2014_9. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.6Å

Function

CED9_CAEEL Plays a major role in programmed cell death (PCD, apoptosis). Egl-1 binds to and directly inhibits the activity of ced-9, releasing the cell death activator ced-4 from a ced-9/ced-4 containing protein complex and allowing ced-4 to activate the cell-killing caspase ced-3.[1] [2] [3] [4] [5] [6]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
