Summary: The oncogene BCL2 is 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 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. Multiple protein isoforms are encoded by this mRNA through the use of a non-AUG (CUG) initiation codon, and three alternative downstream AUG initiation codons. A related pseudogene has been defined on chromosome X. [provided by RefSeq, Feb 2010]

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.

NM_001172415.2 → NP_001165886.1 BAG family molecular chaperone regulator 1 isoform BAG-1S

Status: REVIEWED

Description

Transcript Variant: This transcript (1) encodes multiple isoforms due to the use of alternative translation initiation codons. The longest isoform (BAG-1L or p50) is derived from an upstream non-AUG (CUG) start codon, while three shorter isoforms are derived from downstream AUG start codons. The most abundant of the shorter isoforms (BAG-1S, also known as p33 or p36), which is derived from the second downstream AUG start codon, is represented in this RefSeq.
