Recombinant Human MSI2 Protein

Product Name: Recombinant Human MSI2 Protein
Catalog #:  HTF-1906
Manufacture:  LD Biopharma, Inc.

Human RNA-binding protein Musashi homolog 2 (MSI2) gene encodes an RNA-binding protein that is a member of the Musashi protein family. The encoded protein is transcriptional regulator that targets genes involved in development and cell cycle regulation. It may play a role in the proliferation and maintenance of stem cells in the central nervous system. Recent data indicated that MSI2 is very important factor for expand HSC in vitro. Mutations in this gene are associated with poor prognosis in certain types of cancers. This gene has also been shown to be rearranged in certain cancer cells.

Full-length human MSI2 cDNA (327aa, Isoform-A) was constructed with codon optimization using gene synthesis technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. It was expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.

1. May be used for in vitro MSI2 mediated gene transcription regulation for HSC or neuronal cell’s differentiation study by intracellular delivery of this protein with protein-delivery reagent such as “ProFectin” reagent kit.

2. May be used for mapping MSI2 protein-protein interaction.

3. May be used as specific substrate protein for kinase, and ubiquitin (Sumo pathway) related enzyme functional screening assays.

4. Potential biomarker protein for cancer prognosis, such as adult B-acute lymphoblastic leukemia.

5. As immunogen for specific antibody production.
