BOB.1 is a B-cell specific coactivator and interacts with OCT.1 and OCT.2 transcription factors. The expression of BOB.1 is limited largely to mature B-cells in germinal centers and mantle zones, as well as plasma cells. The expression of BOB.1 in B-cell tumors is variable. Lymphocyte predominant (LP) cells in nodular lymphocyte predominant Hodgkin lymphoma are BOB.1 positive. In B-cell lymphomas, the highest expression levels for BOB.1 are in follicle center lymphomas, diffuse large B-cell lymphomas (DLBCL) and Burkitt lymphomas.
The neoplastic cells in this classical Hodgkin lymphoma show no, or only very weak, nuclear staining
for BOB.1.
