Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
msi is required in spermatocytes for correct meiotic chromosome segregation and cytokinesis.
RNAi generated by PCR using primers directed to this gene causes a cell growth and viability phenotype when assayed in Kc167 and S2R+ cells.
msi protein acts as a translational repressor of ttk in the neuronal lineage, acting in the 3' untranslated region of the ttk mRNA. N signalling does not affect msi expression, though msi can act downstream of N, therefore N signalling is more likely to regulate msi activity than its expression.
msi is required for the development of adult external sensory organs (sensilla). msi mutation typically results in extra sockets and/or shafts. It is suggested that the msi phenotype results from transformation of a neuron/glial-precursor cell into a second shaft/socket-precursor cell. It is proposed that the msi protein regulates sensillum development by controlling the expression of target genes at the post-transcriptional level.
msi is required for development of adult external sensory organs (sensilla). Mutations in msi result in the appearance of extra outer support cells. It is proposed that the msi protein regulates sensillum development by controlling the expression of target genes at the posttranscriptional level.
The mutant is referred to as musashi, owing to the frequent double-shaft phenotype. Typical samuri warriors used only one sword, Musashi Miyamoto originated the style of fighting using two swords simultaneously.
