  • 產(chǎn)品描述：

    POU2AF1 is a gene that was previously thought to be expressed only in lymphocytes, where it regulates immunoglobin production and other host defense-related genes as a co-activator of octamer-binding transcription factors OCT1 and OCT2. POU2AF1 has no intrinsic DNA binding activity but can recognize the POU domain of OCT1 and OCT2. It plays an essential role in B-cell responses to antigens and is required for the formation of germinal centers. In addition to modulating the IgG gene in B cells, POU2AF1 contains numerous known downstream genes with various functions in lymphocytes, including cellular metabolism, cell survival, surface receptors, ion transport, and cell adhesion.

    CUSABIO cloned POU2AF1 antibody-coding genes into plasma vectors and then transfected these vector clones into mammalian cells using a lipid-based transfection reagent. Following transient expression, the recombinant antibodies against POU2AF1 were harvested and characterized. The recombinant POU2AF1 antibody was purified by Affinity-chromatography from the culture medium. It can be used to detect POU2AF1 protein from Human in the ELISA, WB, IHC.

靶點詳情

  • 功能：
    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.

    1. The number of follicular B2 lymphocytes and expression of the B-cell-specific transcriptional coactivator OcaB increase with age in spleen and in intra-abdominal epididymal white adipose tissue (eWAT), concomitantly with higher circulating levels of IgG and impaired glucose homeostasis. PMID: 29496744
    2. These findings demonstrate for the first time that functional polymorphism in the 3'-UTR of POU2AF1 is associated with susceptibility, and that single-nucleotide polymorphisms interaction with hsa-miR-633 affects gene expression and increases the risk of lymphoma. PMID: 28345816
    3. Oct2 and Bob1 are very reliable in determining B cell lineage in the absence of expression of other pan-B cell markers PMID: 27319306
    4. these findings suggest a novel function of POU2AF1 as a potential regulator of host defense genes in the human airway epithelium. PMID: 26927796

    8. 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. PMID: 21549311
    9. On multivariate analysis, co-expression of OCT-2/BOB.1 remained predictive for achievement of complete remission and increased risk of relapse. PMID: 20141429
    10. BOB.1 may be helpful marker in the differential diagnosis of classical Hodgkin's lymphoma and primary mediastinal B-cell lymphoma PMID: 20102401
    11. The expression of the octamer cofactor gene OBF-1 (Bob1/OCA-B) is sufficient to override the silencing effects of the B29 silencer, indicating that OBF-1 plays a critical role in B cell-specific B29 promoter expression. PMID: 11907094
    12. enhances transcriptional potential of Oct1 PMID: 12727885
    13. OCA-B sustains expression of the immunoglobulin-secreting program when T lymphoma and plasmacytoma lines are fused, requiring Oct-2 coregulator for its function. PMID: 14662861
