products description :

Bag1 belongs to the Bcl-2 associated athanogene (BAG) family of multifunctional proteins and was the first of six related proteins isolated from humans (1,2). This widely expressed protein interacts with a number of signaling molecules (including Bcl2, HGF receptor and Raf1) as it regulates signaling molecules in pathways involving cell survival, growth and differentiation. The most common role played by Bag1 protein is as an inhibitor of proteins favoring apoptosis (2-4). Bag1 also plays a role in Raf1 signaling and binds DNA as a transcription activator (4). Bag1 protein is a well-characterized inhibitor of its binding partner HSP70 (5). A conserved carboxy-terminal BAG domain within Bag1 interacts with the ATPase domain of HSP70 to negatively regulate heat shock protein chaperone activity (6,7). The multiple isoforms of Bag1 protein generated from a single transcript share a common ubiquitin homology domain and a carboxy-terminal Hsp70 binding region but differ in length and cellular localization. The 50 kDa long (Bag1-L) isoform also contains a nuclear localization signal and is often found in the nucleus where it activates transcription. The 46 kDa intermediate (Bag1-M) isoform is found mainly in the cytoplasm but can also translocate to the nucleus when associated with other proteins. The shorter 29-33 kDa isoforms (Bag1-S, Bag-1) isoforms are found primarily in the cytoplasm (8). High expression of the anti-apoptotic Bag1 protein correlates with increased survival in patients with particular forms of cancer, leading researchers to study possible therapeutic roles for Bag1 protein (9)

ncbi 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]

uniprot summary :

BAG1: Inhibits the chaperone activity of HSP70/HSC70 by promoting substrate release. Inhibits the pro-apoptotic function of PPP1R15A, and has anti-apoptotic activity. Markedly increases the anti-cell death function of BCL2 induced by various stimuli. Homodimer. Forms a heteromeric complex with HSP70/HSC70. Binds to the ATPase domain of HSP/HSC70 chaperones. Isoform 1, isoform 3 and isoform 4 but not isoform 2 interact with HSPA8/HSC70. Interacts with NR3C1. Interacts with the N-terminal region of STK19. Interacts with PPP1R15A. Interacts with BCL2 in an ATP-dependent manner. Isoform 2 does not interact with BCL2. Up-regulated during differentiation of bladder epithelial cells and down-regulated during differentiation of prostate epithelium. Isoform 4 is the most abundantly expressed isoform. It is ubiquitously expressed throughout most tissues, except the liver, colon, breast and uterine myometrium. Isoform 1 is expressed in the ovary and testis. Isoform 4 is expressed in several types of tumor cell lines, and at consistently high levels in leukemia and lymphoma cell lines. Isoform 1 is expressed in the prostate, breast and leukemia cell lines. Isoform 3 is the least abundant isoform in tumor cell lines. 4 isoforms of the human protein are produced by alternative splicing. Protein type: Nuclear receptor co-regulator; Motility/polarity/chemotaxis. Chromosomal Location of Human Ortholog: 9p12. Cellular Component: cytoplasm; nucleus. Molecular Function: protein binding; chaperone binding; receptor signaling protein activity. Biological Process: cell surface receptor linked signal transduction; apoptosis; negative regulation of apoptosis
