Crystal structure of CED-4 bound CED-3 fragment

Template:ABSTRACT PUBMED 24065769

Function

[CED4_CAEEL] Isoform a 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. Isoform b prevents PCD.[1] [2] [3] [4] [5]

About this Structure

4m9x is a 4 chain structure with sequence from Xenopus itombwensis. Full crystallographic information is available from OCA.
