Spi-1Proto-Oncogene, also known as SPI1, owns ETS-domain transcription factor whichactivates gene expression during myeloid and Blymphoid cell development. SPI1 bindsto a purine-rich sequence called the PU-box which is located near the promotersof target genes, and regulates their expression. SPI1 binds RNA and modulatepre-mRNA splicing. SPI1 is also regulates alternative splicing of targetgenes.
SPI1 Human Recombinant produced in E. coli is a single polypeptide chain containing 294 amino acids (1-271) and having a molecular mass of 33.6kDa.SPI1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
| UniProt Protein Function: | PU.1: Binds to the PU-box, a purine-rich DNA sequence (5'- GAGGAA-3') that can act as a lymphoid-specific enhancer. This protein is a transcriptional activator that may be specifically involved in the differentiation or activation of macrophages or B- cells. Also binds RNA and may modulate pre-mRNA splicing. Binds DNA as a monomer. Interacts with CEBPD and NONO. Interacts with RUNX1 and SPIB. Interacts with GFI1; the interaction represses SPI1 transcriptional activity. Highly expressed in both FV-P and FV-A-induced erythro- leukemia cell lines that have undergone rearrangements of the Spi- 1 gene due to the insertion of SFFV. Belongs to the ETS family. 2 isoforms of the human protein are produced by alternative splicing. |

| NCBI Summary: | This gene encodes an ETS-domain transcription factor that activates gene expression during myeloid and B-lymphoid cell development. The nuclear protein binds to a purine-rich sequence known as the PU-box found near the promoters of target genes, and regulates their expression in coordination with other transcription factors and cofactors. The protein can also regulate alternative splicing of target genes. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008] |
