BCL2A1 Research Reagents

Bcl-2-related protein A1 is a protein in humans that is encoded by BCL2A1 gene. Retards apoptosis induced by IL-3 deprivation. May function in the response of hemopoietic cells to external signals and in maintaining endothelial survival during infection (By similarity). Can inhibit apoptosis induced by serum starvation in the mammary epithelial cell line HC11 (By similarity).

BCL2A1 Background

Bcl-2-related protein A1 also called Bcl-2 related gene expressed in fetal liver (Bfl-1), is a protein in humans that is encoded by the BCL2A1 gene on chromosome 15q24.3 [1]. BCL2A1 possesses four BH-domain: BH1-BH4. Crystal structures of BCL2A1 in complex with BH3-peptides revealed that it displays a similar hydrophobic groove as observed on all related anti-apoptotic Bcl-2 (B-cell lymphoma 2) proteins [2]. Although BCL2A1 does not exhibit a well-defined C-terminal transmembrane domain identified in other anti-apoptotic Bcl-2 proteins, its C-terminus is essential for the anti-apoptotic function and the subcellular localization of BCL2A1 [3]. BCL2A1 protein is particularly important in the hematopoietic system [10] and executes its anti-apoptotic function by sequestering pro-apoptotic BCL2 proteins [4]. The transcription of BCL2A1 is induced by NF-kappa B[5], retinoic X receptors (RXR) agonists [6], and WT-1 [7], but inhibited by the plasma cell transcription factor PRDI-BF1/Blimp-1 [8]. The identification of BCL2A1 as an NF-κB target gene shows that the formation of inflammasomes may also induce the expression of BCL2A1, thus promoting the survival of the pro-inflammatory cells during inflammation. The stability of BCL2A1 protein is regulated by proteasomal degradation [9]. BCL2A1 overexpression has been found in various hematological malignancies [10] as well as solid tumors [11] and seems to be notably associated with advanced or metastatic disease stages [12]. Besides a potential role in tumorigenesis, BCL2A1 overexpression is also involved in the resistance for chemotherapy.
