Western blot - Anti-EBNA2 antibody [PE2] (AB90543)

EBNA2 western blot using Anti-EBNA2 antibody [PE2] ab90543. Publication image and figure legend from Zvejniece, L., Kozireva, S., et al., 2022, International Journal of Molecular Sciences PubMed 35408790.

Phenotype of the Burkitt lymphoma cell lines. The percentages (%) of CD10-positive (A) and CCR1-expressing (B) cells were obtained using flow cytometry analysis. Annexin V-stained (apoptotic) and autofluorescent cells were omitted from the analysis. The presented data are from at least two independent experiments and are shown as the mean with the SD. (C) The IGHV gene identity (%) to the top germline genes was defined using the NCBI IGBLAST Tool. (D) EBNA2 and LMP1 protein expression in the type II and type III BL cell lines was assessed using immunoblotting of cell lysates and specific antibodies; the human beta-actin protein was probed as the loading control. The Raji and Mutu III BL type II cell lines served as the positive control (Table S1). All clones of the Mutu cell line are derivatives of an early-passage BL cell line [14]. BL41 is an EBV-negative cell line. A small panel, the same immunoblot with prolonged exposure, shows the EBNA2 protein in the cell lines BL41/95, BL16, Akuba, and Raji. (E) Immunofluorescent staining of CCR1 is shown in cells of the type III BL cell line Mutu cl.99 and human myeloid histiocytic lymphoma cell line U937, used as the positive control; in DG75, the EBV and the CCR1 transcript negative BL cell line, the CCR1 immunofluorescent signal was not observed.

EBNA2 also known as the Epstein-Barr virus nuclear antigen 2 (EBNA-2) plays a critical role in viral protein function. It is a transcriptional activator essential for the latent infection cycle of Epstein-Barr virus (EBV). EBNA2 binds to specific DNA sequences and interacts with other host cellular factors to initiate transcription. The molecular mass of EBNA2 typically is approximately 88 kDa. EBNA2 mainly expresses in EBV-infected B lymphocytes where it contributes to their immortalization and proliferation.
Biological function summary

EBNA2 is pivotal in the activation of several viral and cellular genes. It forms complexes with other proteins including the cellular transcription factor RBP-Jκ part of the Notch signaling pathway. This interaction is important for altering the expression patterns of both host and viral genes causing changes in the cell cycle and promoting latency. EBNA2 also regulates genes involved in immune response modulation aiding in viral persistence within the host by evading immune surveillance.

Pathways

EBNA2 impacts transcriptional regulation and cell signaling reversibly. It is integral to the Notch signaling and transcriptional activation pathway related to EBV latency. EBNA2 recruits proteins like CBF1 (RBP-Jκ) a transcription factor that helps mediate cell fate decisions and maintain latency. It modulates pathways involving c-MYC a central regulator of cell growth and influences transcriptional activity with a downstream effect on cellular transformation and proliferation.

EBNA2 is prominently associated with EBV-related malignancies such as Burkitt's lymphoma and Hodgkin's lymphoma. These cancers arise partly from the dysregulated cellular growth induced by EBNA2-mediated transcriptional changes. In these disorders EBNA2 may interact with proteins like LMP1 another EBV-encoded protein that aids in the transformation process promoting oncogenesis and affecting therapy resistance mechanisms.

Target data

Plays a key role in the activation of the host resting B-cell and stimulation of B-cell proliferation. Acts by up-regulating the expression of viral EBNA1-6, LMP1, LMP2A and LMP2B genes, as well as several host genes including CD21, CD23 and MYC. Activates transcription by acting as an adapter molecule that binds to cellular sequence-specific DNA-binding proteins such as host CBF1, SMARCB1 and SPI1. Once EBNA2 is near promoter sites, its acidic activating domain recruits basal and activation-associated transcription factors TFIIB, TAF40, TFIIH components ERCC2 and ERCC3, and CBP in order to promote transcription. Alternatively, EBNA2 can affect activities of cell cycle regulators and retard cell cycle progression at G2/M phase. It also induces chromosomal instability, by disrupting mitotic checkpoints, multi-nucleation and formation of micronuclei in infected cells.
