  • Experimental Validation Results for PU.1/SPI1 Antibody (YA118)
    Western blot analysis of extracts from MCF-7(lane 2(20μg) , THP-1(lane 3(20μg) ,HUVEC(lane 4(20μg)and Raji( lane 5(20μg) using PU.1/SPI1 Antibody (HY-P80287). Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody ( 1/500) and Loading control antibody (Beta Actin, HY-P80993,1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (HY-P8001,1/10,000) was used for 1 hour at room temperature.
  • Experimental Validation Results for PU.1/SPI1 Antibody (YA118)
    Immunohistochemical analysis of paraffin-embedded human Tonsil tissue using PU.1/SPI1 antibody was performed. The section was pretreated using high-temperature and high-pressure mediated EDTA antigen retrieval buffer (pH 9.0), for 5 minutes. The tissues were incubated with primary antibody (HY-P80287, 1:1000 dilution) at room temperature for 60 minutes. Detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. The tissues were counterstained with hematoxylin and mounted with neutral balsam mounting medium.

Background

  • Function

    Pioneer transcription factor, which controls hematopoietic cell fate by decompacting stem cell heterochromatin and allowing other transcription factors to enter otherwise inaccessible genomic sites. Once in open chromatin, can directly control gene expression by binding genetic regulatory elements and can also more broadly influence transcription by recruiting transcription factors, such as interferon regulatory factors (IRFs), to otherwise inaccessible genomic regions (PubMed:23658224, PubMed:33951726). Transcriptionally activates genes important for myeloid and lymphoid lineages, such as CSF1R (By similarity). Transcriptional activation from certain promoters, possibly containing low affinity binding sites, is achieved cooperatively with other transcription factors. FCER1A transactivation is achieved in cooperation with GATA1 (By similarity). May be particularly important for the pro- to pre-B cell transition (PubMed:33951726). Binds (via the ETS domain) onto the purine-rich DNA core sequence 5'-GAGGAA-3', also known as the PU-box (PubMed:33951726). In vitro can bind RNA and interfere with pre-mRNA splicing (By similarity)

  • Subcellular Localization

    Nucleus

  • Expression


    Tissue_specificity:In the bone marrow, it is mainly concentrated in hematopoietic stem cells, lymphoid progenitor cells, myeloid cells (granulocyte-macrophage progenitor cells, classical dendritic cells, monocytes) , and B cell clusters. Among B cells, it is primarily expressed in pre-B1 cells (PubMed: 33951726) . It is also expressed in germinal center B cells (PubMed: 23166356) .

    Induction:Highly expressed in both FV-P and FV-A-induced erythro-leukemia cell lines that have undergone rearrangements of the SPI1 gene due to the insertion of SFFV. Negatively regulated by microRNA-155 (miR-155) (PubMed:23166356)

  • Isoforms & Post-Translational Modification

    P17947 has 2 isomers: P17947-1: 31083 Da (predicted); P17947-2: 31211 Da (predicted).

  • Subunit

    Binds DNA as a monomer. Can form homomers (PubMed:10196196). Directly interacts with CEBPD/NF-IL6-beta; this interaction does not affect DNA-binding properties of each partner (By similarity).
