Binding of pumilio to maternal hunchback mRNA is required for posterior patterning in drosophila embryos

Posterior patterning in Drosophila embryos is governed by nanos (nos), which acts by repressing the translation of maternal transcripts of the hunchback ( hb) gene. Sites in hb mRNA that mediate this repression, named nanos response elements (NREs), have been identified. However, we know of no evide...
