A synthetic peptide from human BAD
A synthesized peptide derived from human BAF250B, corresponding to a region within the internal amino acids.
A synthesized peptide derived from human BAFF, corresponding to a region within N-terminal amino acids.
Tumor necrosis factor receptor superfamily,member 13C (TNFRSF13C) also known as B-cell-activating factor receptor (BAFFR) and CD268 antigen,is a member of the tumor necrosis factor receptor superfamily. BAFF promotes the survival of B cells and is essential for B cell maturation. BAFF binds to three TNF receptor superfamily members: B-cell maturation antigen (BCMA/TNFRSF17),transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI/TNFRSF13B) and BAFF receptor (BAFF R/BR3/TNFRSF13C). These receptors are type III transmembrane proteins that lack a signal peptide. BAFF R is highly expressed in spleen,lymph node and resting B cells. It is also expressed at lower levels in activated B cell,in resting CD4+ T cells,in thymus and peripheral blood leukocytes. BAFF knockout mice lack mature B cells. Similarly,A/WySnJ mice that are defective in BAFF-R intracellular signaling also lack mature B cells,suggesting that BAFF R is the critical receptor for BAFF during B lymphopoiesis. It has been proposed that abnormally high levels of BAFFR/TNFRSF13C (CD268) may contribute to the pathogenesis of autoimmune diseases by enhancing the survival of autoreactive B cells.
A synthesized peptide derived from human Bag 1, corresponding to a region within N-terminal amino acids.
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.
