== Function ==
[https://www.uniprot.org/uniprot/B2LA1_MOUSE B2LA1_MOUSE] Retards apoptosis induced by IL-3 deprivation. May function in the response of hemopoietic cells to external signals and in maintaining endothelial survival during infection. Can inhibit apoptosis induced by serum starvation in the mammary epithelial cell line HC11 (PubMed:11888890).<ref>PMID:11888890</ref>

== 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<ref>PMID:18462686</ref>
