VPREB1: VPREB1 Protein | VPREB1 Antibody

VPREB1 Gene family

VPREB1 Background

VPREB1 gene, a component of the surrogate light chain of the pre-B-cell receptor (pre-BCR), have been observed in childhood B-cell acute lymphoblastic leukemia (B-ALL), and have been suggested to result from recombination activating gene (RAG) activation. Studies show that a low copy number of the VPREB1 gene is related to the pathogenesis of RA and other autoimmune disorders. Moreover, the VpreB1 can act as an enhancer to ensure developmental stage-specific expression of a reporter gene in B lymphocytes in vivo.

VPREB1 Protein

VPREB1 protein function

Associates with the Ig-mu chain to form a molecular complex that is expressed on the surface of pre-B-cells. This complex presumably regulates Ig gene rearrangements in the early steps of B-cell differentiation.
