WebDec 3, 1993 · The lin-14 3′UTR is both necessary and sufficient to confer lin-4 -mediated posttranscriptional temporal regulation. The function of the lin-14 3′UTR is conserved … WebDec 15, 2010 · Transcription and multiple processing steps are required to produce specific 22 nucleotide microRNAs (miRNAs) that can regulate the expression of target genes. In C. elegans, mature lin-4 miRNA accumulates at the end of the first larval stage to repress its direct targets lin-14 and lin-28, allowing the progression of several somatic cell types ...
WebSep 13, 2013 · In Caenorhabditis elegans, the lin-4 miRNA accumulates during early larval development, binds to target elements in the lin-14 mRNA, and causes a sharp decrease in the abundance of LIN-14 protein. Here, we monitor the dynamics of lin-14 mRNA and protein as well as lin-4 miRNA levels in finely staged animals during early larval … Webb. lin-4 encodes a RNA-binding protein and regulates the splicing of lin-14. c. lin-4 encodes a non-coding RNA and inhibits the translation of lin-14 mRNA. d. lin-4 encodes a non-coding RNA and affects the stability of lin-14 mRNA. e. lin-4 encodes a helix-turn-helix motif-containing transcription factor and represses the expression of lin-14.
WebThe interaction of lin-4 and lin-14 and their effect on the timing of development in C. elegans set a precedent for the study of another miRNA, let-7, which is expressed later in development. let-7 controls the L4-to-adult transition in C. elegans development by interacting with the 3' UTR of multiple target genes, including lin-41 . Weblin-4 S RNA is 22 nucleotides long and contains two blocks of sequences that are complementary to an element repeated seven times in the 3′UTR …
WebThe heterochronic genes lin-4, lin-14, lin-28, and lin-29 control the timing of specific postembryonic developmental events in C. elegans [4]. Gain-of-function lin-14 mutations cause the level of lin-14 protein to remain high throughout development, resulting in developmental reiterations of early cell lineages [5].
