    Product Description

    B cell Oct Binding Factor 1 (BOB-1) is a transcription factor that has a role in B cell development and function.1 It contains a polypeptide region, a two-turn α-helix, and a disordered region.2 It is primarily expressed on B cells, with the highest expression in germinal center B cells, and transiently expressed on activated T cells.1 Its expression is induced by downstream signaling of B cell receptors, as well as IL-4, CD40 ligand (CD40L), and LPS.3 BOB-1 is a coactivator that is recruited to the POU domain of the transcription factors Oct-1 and Oct-2 and enhances their transactivation.1 Mice deficient in POU2AF1, the gene encoding BOB-1, have reduced numbers of transitional and mature B cells and lack a marginal zone B cell compartment and germinal center in the bone marrow, leading to deficits in secondary immunoglobulin isotype production.3,4 POU2AF1 is downregulated in classical, but not lymphocyte-predominant, Hodgkin lymphoma.5 Cayman’s BOB-1/OBF-1 (C-Term) Rabbit Monoclonal Antibody (Clone RM378) can be used for immunohistochemistry (IHC) and Western blot (WB) applications.
