Grossbard et al., New York City, United States. In Clin Lymphoma Myeloma Leuk, 2014
It is characterized histologically by presence of lymphohistiocytic cells which have B-cell phenotype, are positive for CD19, CD20, CD45, CD79a, BOB.1, Oct.2, and negative for CD15 and CD30.
Discovery and characterization of super-enhancer-associated dependencies in diffuse large B cell lymphoma.
Bradner et al., Boston, United States. In Cancer Cell, 2014
Functional study of genes marked by super-enhancers identifies DLBCLs dependent on OCA-B and suggests a strategy for discovering unrecognized cancer dependencies.
Epstein-Barr virus-positive diffuse large B-cell lymphomas of the elderly.
Quintanilla-Martínez et al., Tübingen, Germany. In Adv Anat Pathol, 2011
Strong, homogeneous expression of B-cell markers, including transcription factors OCT2 and BOB.1, and lack of CD15 support a diagnosis of EBV+ DLBCL.
Direct interactions of OCA-B and TFII-I regulate immunoglobulin heavy-chain gene transcription by facilitating enhancer-promoter communication.
Roeder et al., New York City, United States. In Mol Cell, 2011
Data show that Igh 3' enhancer-bound OCA-B and promoter-bound TFII-I mediate promoter-enhancer interactions, in both cis and trans, that are important for Igh transcription.
B-cell transcription factors Pax-5, Oct-2, BOB.1, Bcl-6, and MUM1 are useful markers for the diagnosis of nodular lymphocyte predominant Hodgkin lymphoma.
Ioniţă et al., Timişoara / Temesvár, Romania. In Rom J Morphol Embryol, 2010
Twenty-two cases of nodular lymphocyte predominant Hodgkin lymphoma were studied for the immunohistochemical expression of Pax-5, Oct-2, BOB.1, Bcl-6 protein and MUM1/IRF-4.

Histologically, the tumor cells exhibited plasmablastic morphology with expression of Bob-1, CD4, CD10, CD45, CD56, CD138, EMA, MUM1, Oct-2, and kappa immunoglobulin light chain, but negative for CD20, CD30, CD79a, PAX-5, and lambda.
B-cell lymphomas with features intermediate between distinct pathologic entities. From pathogenesis to pathology.
Cabras et al., Milano, Italy. In Hum Pathol, 2010
Alternatively, these cases may resemble primary mediastinal large B-cell lymphoma but contain tumor cells resembling Reed-Sternberg cells and displaying an aberrant phenotype such as CD20(-), CD15(-/+) CD45(+), CD30(+), Pax5(+), OCT2(+/-), and BOB1(+/-).
OCT-2 expression and OCT-2/BOB.1 co-expression predict prognosis in patients with newly diagnosed acute myeloid leukemia.
Hsi et al., Cleveland, United States. In Leuk Lymphoma, 2010
On multivariate analysis, co-expression of OCT-2/BOB.1 remained predictive for achievement of complete remission and increased risk of relapse.
BOB.1, CD79a and cyclin E are the most appropriate markers to discriminate classical Hodgkin's lymphoma from primary mediastinal large B-cell lymphoma.

Nontranscriptional regulation of SYK by the coactivator OCA-B is required at multiple stages of B cell development.
Roeder et al., New York City, United States. In Cell, 2006
Results suggest that OCA-B is required for pre-BCR and BCR signaling at multiple stages of B cell development through its nontranscriptional regulation of SYK.
OcaB is required for normal transcription and V(D)J recombination of a subset of immunoglobulin kappa genes.
Nussenzweig et al., New York City, United States. In Cell, 2002
OcaB is essential for V(D)J recombination of a subset of Igkappa genes. We show that OcaB modulates recombination by directly enhancing Igkappa gene transcription in vivo.
Identification and characterization of a novel OCA-B isoform. implications for a role in B cell signaling pathways.
Roeder et al., New York City, United States. In Immunity, 2001
OCA-B is a B lymphocyte-specific transcription coactivator that mediates tissue- and stage-restricted transcription of immunoglobulin genes.
Synergism with the coactivator OBF-1 (OCA-B, BOB-1) is mediated by a specific POU dimer configuration.
Schöler et al., United States. In Cell, 2001
The POU dimer formed on the PORE (ATTTGAAATGCAAAT) can recruit the transcriptional coactivator OBF-1, whereas POU dimers formed on the consensus MORE (ATGCATATGCAT) or on MOREs from immunoglobulin heavy chain promoters (AT[G/A][C/A]ATATGCAA) fail to interact.
