Web[4] lin-4 is found on chromosome II in C. elegans and is complementary to sequences in the 3' untranslated region (UTR) of lin-14 mRNA, this complementary transcript containing seven binding sites along with the 9 nucleotide core element CUCAGGGAA. WebThis suggests that lin-4 down-regulates lin-14 transla- tion by forming multiple RNA duplexes with the lin-14 mRNA (Wightman et al. 1993).
