RIPAb+ Musashi 1 - RIP Validated Antibody and Primer Set, rabbit monoclonal
Overview
RIPAb+ antibodies are evaluated using the RNA Binding Protein Immunoprecipitation (RIP) assay. Each RIPAb+ antibody set includes a negative control antibody to ensure specificity of the RIP reaction and is verified for the co-immunoprecipitation of RNA associated specifically with the immunoprecipitated RNA binding protein of interest. Where appropriate, the RIPAb+ set also includes quantitative RT-PCR control primers (RIP Primers) to biologically validate your IP results by successfully co-precipitating the specific RNA targets, such as messenger RNAs. The qPCR protocol and primer sequences are provided, allowing researchers to validate RIP protocols when using the antibody in their experimental context. If a target specific assay is not provided, the RIPAb+ kit is validated using an automated microfluidics-based assay by enrichment of detectable RNA over control immunoprecipitation.
Alternate Names
Musashi (Drosophila) homolog 1

musashi homolog 1 (Drosophila)
Background Information
In mammals, the Musashi family is important for cell fate determination, playing roles in maintenance of the stem-cell state, differentiation and tumorigenesis. Musashi-1 (also known as Msi1), is selectivley expressed in neural progenitor cells, including neural stem cells. Outside the nervous system, Musashi-1 is a selective marker for intestinal stem or early lineage cells. Musashi-1 interacts with the Notch pathway during asymmetric cell division by binding the 3' UTR of Numb. Numb is prevented from repressing Notch signaling when Musashi-1 is present.

Application Notes
Immunoprecipitation from RIP lysate: Representative lot data. RIP lysate from SHSH-5Y cells (2 X 10E6 cell equivalents per IP) was subjected to immunoprecipitation using 0.5 µL of either a normal rabbit IgG or 0.5 µL of Anti-Musashi 1 antibody. Precipitated proteins (lane 1: rabbit IgG, lane 2: anti-Musashi 1) and SHSH-5Y whole cell lysate (lane 3) were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-Musashi 1 antibody (1:2,000 dilution). Proteins were visualized using One-Step™ IP-Western kit (GenScript). Arrow indicates Musashi 1 (Please see figures).
Immunocytochemistry Analysis: Representative lot data. A previous lot of this antibody was used in immunofluorescent staining of PC12 cells using Anti-Musashi 1 (Please see figures).
Immunohistochemistry (Paraffin) Analysis: Representative lot data. A previous lot of this antibody was used in immunohistochemical staining of paraffin-embedded human brain using Anti-Musashi 1 (Please see figures).
Western Blot Analysis: Representative lot data. SHSY5Y cell lysate was resolved by electrophoresis, transferred to PVDF membrane and probed with Anti-Musashi 1 (1:2,000 dilution). Proteins were visualized using a Goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system. Arrow indicates Musashi 1 (~39 kDa) (Please see figures).
Flow Cytometry: A 1:40 dilution of a previous lot was used in flow cytometry.
Biological Information
Immunogen
Synthetic peptide corresponding to residues on the N-terminus of human Musashi-1.
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.
FUNCTION: 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 By similarity. SUBCELLULAR LOCATION: Cytoplasm By similarity. Nucleus By similarity. TISSUE SPECIFICITY: Detected in fetal kidney, brain, liver and lung, and in adult brain and pancreas. Detected in hepatoma cell lines. DOMAIN: The first RNA recognition motif binds more strongly to RNA compared to the second one By similarity. SEQUENCE SIMILARITIES: Belongs to the Musashi family. Contains 2 RRM (RNA recognition motif) domains.

Increased particulate phosphodiesterase 4 in the prefrontal cortex supports 5-HT4 receptor-induced improvement of object recognition memory in the rat. Guénaëlle Levallet,Maïté Hotte,Michel Boulouard,François Dauphin Psychopharmacology

Serotonin receptors (5-HT4Rs) are critical to both short-term and long-term memory processes. These receptors mainly trigger the cyclic adenosine monophosphate (cAMP)/protein kinase A signaling pathway, which is regulated by cAMP phosphodiesterases (PDEs).
Inhibition of Bacillus subtilis and Listeria innocua by nisin in combination with some naturally occurring organic compounds. N A Olasupo,D J Fitzgerald,A Narbad,M J Gasson Journal of food protection

2004
The application of combined preservative factors (hurdle technology) is very effective in controlling the growth of food spoilage and foodborne pathogenic bacteria. Antimicrobial activity of nisin alone and in combination with some natural organic compounds (carvacrol, cinnamic acid, eugenol, diacetyl, and thymol) on the growth of gram-positive bacteria Bacillus subtilis and Listeria innocua was-investigated. All the organic compounds tested exhibited antimicrobial activity against the microorganisms used; however, the MICs varied between 0.8 and 15.0 mM depending on the potency of the compound or the sensitivity of the target strain. Investigation of the interaction between the organic compounds and nisin against the test organisms revealed different patterns, varying from synergistic to antagonistic. Combinations of nisin with carvacrol, eugenol, or thymol resulted in synergistic action against both test organisms. Activity of nisin and cinnamic acid together was synergistic against L. innocua, but only additive against B. subtilis. In contrast, the combination of diacetyl and nisin resulted in an antagonistic effect against both test organisms. This study highlights the potential of the combination of these compounds with nisin to inhibit pathogen growth in food.
