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. At least three protein isoforms are encoded by this [[mRNA]] through the use of alternative [[Translation (biology)|translation]] initiation sites, including a non-[[start codon|AUG]] site.<ref name="entrez">{{cite web | title = Entrez Gene: BAG1 BCL2-associated athanogene| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=573| accessdate = }}</ref>

BAG family molecular chaperone regulator 1 is a protein that in humans is encoded by the BAG1 gene.[5]

Function

[edit]

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. At least three protein isoforms are encoded by this mRNA through the use of alternative translation initiation sites, including a non-AUG site.[6]

Clinical significance

[edit]

BAG gene has been implicated in age related neurodegenerative diseases as Alzheimer's. It has been demonstrated that BAG1 and BAG 3 regulate the proteasomal and lysosomal protein elimination pathways, respectively.[7]

Interactions

[edit]

BAG1 has been shown to interact with:
