POU2AF1 Recombinant Monoclonal Antibody

Uniprot Id

Q16633

Target Species

Human

Target Name

POU2AF1

Target Full Name

POU domain class 2-associating factor 1

Target Function

Transcriptional coactivator that specifically associates with either POU2F1/OCT1 or POU2F2/OCT2. It boosts the POU2F1/OCT1 mediated promoter activity and to a lesser extent, that of POU2F2/OCT2. It has no intrinsic DNA-binding activity. It recognizes the POU domains of POU2F1/OCT1 and POU2F2/OCT2. It is essential for the response of B-cells to antigens and required for the formation of germinal centers. Regulates IL6 expression in B cells as POU2F2/OCT2 coactivator.

Target Involvement

A chromosomal aberration involving POU2AF1/OBF1 may be a cause of a form of B-cell leukemia. Translocation t(3;11)(q27;q23) with BCL6.

Target Subcellular Location

Nucleus.

Target Protein Families

Target Tissue Specificity

B-cell specific. Detected in mainly in spleen, but also in thymus, periphral blood leukocyte and small intestine.
