Summary: Predicted to enable BH domain binding activity and channel activity. Involved in negative regulation of apoptotic process. Acts upstream of or within B cell homeostasis and negative regulation of B cell apoptotic process. Predicted to be located in cytoplasm. Predicted to be active in mitochondrial outer membrane. Is expressed in several structures, including bone; central nervous system; heart; hemolymphoid system; and respiratory system. Orthologous to human BCL2A1 (BCL2 related protein A1).

The findings support a model in which survival is determined by quantitative participation of multiple anti-apoptotic proteins, BCL2, Mcl1, and BCL2A1, rather than by a single anti-apoptotic protein.

This dynamic change in B cell survival mechanisms is unique to Epstein-Barr virus-infected cells and relies on regulation of MCL-1 mitochondrial localization and BFL-1 transcription by the viral EBNA3A protein.

Loss of A1 alone does not impair T cell-driven immune responses. It therefore appears likely that A1 has critical overlapping functions with other pro-survival BCL-2 proteins in T cell immune responses.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
