Summary: The oncogene Bcl2 encodes a membrane protein that blocks a step in a pathway leading to apoptosis or programmed cell death. The protein encoded by this gene binds to Bcl2 protein and is referred to as Bcl2-associated athanogene. It enhances the anti-apoptotic effects of Bcl2 and represents a link between growth factor receptors and anti-apoptotic mechanisms. At least two protein isoforms are encoded by this mRNA through the use of a non-AUG (CUG) start site and an alternative, downstream, AUG translation initiation site. [provided by RefSeq, Jul 2008]

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.

See identical proteins and their annotated locations for NP_001165210.1

Status: REVIEWED

Description

Transcript Variant: This transcript (1) encodes multiple isoforms due to the use of alternative translation initiation codons. The longer isoform (BAG-1L or p50) is derived from an upstream non-AUG (CUG) start codon, while the shorter isoform (BAG-1S or p32) is derived from a downstream AUG start codon. The shorter isoform (1S) is represented in this RefSeq.
