Biological background
Biological context: RNA binding protein that regulates the expression of target mRNAs at the translation level. Regulates expression of the NOTCH1 antagonist NUMB. Binds RNA containing the sequence 5'-GUUAGUUAGUUAGUU-3' and other sequences containing the pattern 5'-[GA]U1-3AGU-3'. May play a role in the proliferation and maintenance of stem cells in the central nervous system.
Expression and localization notes: cellular localization: Nucleus. Cytoplasm., tissue context: Detected in fetal kidney, brain, liver and lung, and in adult brain and pancreas. Detected in hepatoma cell lines..
Common research applications
- Western blotting (WB): Compare MSI1 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of MSI1 in tissue sections, considering fixation and antigen retrieval effects.
- Flow cytometry: Quantify MSI1-positive populations in single-cell suspensions with appropriate gating and controls.
- ELISA: Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.
Notes for experimental interpretation
- Account for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.
- Use positive/negative biological controls where possible (e.g., known-expressing cells/tissues, knockdown/knockout models) and include appropriate secondary-only/isotype controls for imaging workflows.
Additional product notes (from provided fields)
- Specificity: No cross reactivity with other proteins.
- Background: RNA-binding protein Musashi homolog 1 is a protein that in humans is encoded by the MSI1 gene. This gene encodes a protein containing two conserved tandem RNA recognition motifs. Similar proteins in other species function as RNA-binding proteins and play central roles in posttranscriptional gene regulation. Expression of this gene has been correlated with the grade of the malignancy and proliferative activity in gliomas and melanomas. A pseudogene for this gene is located on chromosome 11q13.
- Cross reactivity: No cross-reactivity with other proteins.
- Cellular localization: Nucleus. Cytoplasm.
- Tissue details: Detected in fetal kidney, brain, liver and lung, and in adult brain and pancreas. Detected in hepatoma cell lines.
