An E.coli-derived zebrafish Msi1a/b recombinant protein (amino acids K23-D56) was used as the immunogen for the Zebrafish Msi1 antibody. This antibody will detect the a and b isoforms.
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.
