The Cold Shock Domain Protein Lin-28 Controls Developmental Timing In C. Elegans And Is Regulated By The Lin-4 Rna, Eric Moss, Rosalind Lee, Victor Ambros
Victor R. Ambros
Mutations in the heterochronic gene lin-28 of C. elegans cause precocious development where diverse events specific to the second larval stage are skipped. lin-28 encodes a cytoplasmic protein with a cold shock domain and retroviral-type (CCHC) zinc finger motifs, consistent with a role for LIN-28 in posttranscriptional regulation. The 3'UTR of lin-28 contains a conserved element that is complementary to the 22 nt regulatory RNA product of lin-4 and that resembles seven such elements in the 3'UTR of the heterochronic gene lin-14. Both lin-4 activity and the lin-4-complementary element (LCE) are necessary for stage-specific regulation of lin-28. Deleting the LCE …

Heterochronic Genes, Victor Ambros
Victor R. Ambros
This chapter focuses on our current understanding of the C. elegans heterochronic gene pathway as determined by genetic characterization of the regulatory interactions among the genes (Ambros and Horvitz 1987; Ambros 1989; Liu and Ambros 1989) and recent progress on the cloning, sequencing, and molecular analysis of genes involved in this pathway (Ruvkun et al. 1989; Arasu et al. 1991; Papp et al. 1991; Wightman et al. 1991; Lee et al. 1993; Rougvie and Ambros 1995; E. Moss et al., in prep). Primary emphasis is placed on the developmental decisions controlled by the heterochronic genes, the regulatory interactions among genes …
