Function

[BID_MOUSE] Induces caspases and apoptosis. Counters the protective effect of Bcl-2. The major proteolytic product p15 BID allows the release of cytochrome c.^[1]

Evolutionary Conservation

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

Publication Abstract from PubMed

Apoptotic pathways are regulated by protein-protein interactions. Interaction of the BH3 domains of proapoptotic Bcl-2 family proteins with the hydrophobic groove of prosurvival proteins is critical. Whereas some BH3 domains bind in a promiscuous manner, others exhibit considerable selectivity and the sequence characteristics that distinguish these activities are unclear. In this study, crystal structures of complexes between the prosurvival protein A1 and the BH3 domains from Puma, Bmf, Bak, and Bid have been solved. The structure of A1 is similar to that of other prosurvival proteins, although features, such as an acidic patch in the binding groove, may allow specific therapeutic modulation of apoptosis. Significant conformational plasticity was observed in the intermolecular interactions and these differences explain some of the variation in affinity. This study, in combination with published data, suggests that interactions between conserved residues demarcate optimal binding.

Structural plasticity underpins promiscuous binding of the prosurvival protein A1.,Smits C, Czabotar PE, Hinds MG, Day CL Structure. 2008 May;16(5):818-29. PMID:18462686^[2]
