Total lysates (15 µg protein) from Daudi (Human, Positive control), Jurkat (Human, Negative control) and A20 (Mouse) were resolved by electrophoresis (4-20% Tris-glycine gel), transferred to nitrocellulose, and probed with 1:1000 (0.5 µg/ml) purified anti-POU2AF1 antibody, clone 2E9C01. Proteins were visualized using chemiluminescence detection by incubation with HRP Goat anti-Mouse secondary antibody (Cat. No. 405306, 1:3000 dilution). Direct-Blot™ HRP anti-β-actin antibody was used as a loading control (Cat. No. 643807, 1:8000 dilution).

Description

POU2AF1, also known as OBF1, is a B lymphocyte specific transcriptional coactivator. POU2AF1 plays important regulatory roles in the function and maturation of B cells. It stimulates transcription of the immunoglobulin genes by interaction with Oct-1 or Oct-2. The POU2AF1 gene encodes a single mRNA that produces two isoforms, p34 and p35, by post-translational processing. Both isoforms are expressed at similar levels and are able to stimulate octamer-dependent transcription. The cytoplasmic p35 isoform of POU2AF1 regulates pre-B cell proliferation and BCR signaling through interacting with the tyrosine kinase Syk. POU2AF1 deficient mice have shown reduced numbers of circulating B cells in the bone marrow and failed to form germinal centers in the spleen.
