Crystal structures of Nanos bound to Pumilio and target RNAs demonstrate how Nanos forms a molecular clamp to alter Pumilio RNA regulation and specificity in embryonic development and germline maintenance.
Long noncoding RNA Norad performs an essential function in mammalian physiology by inhibiting the activity of PUMILIO RNA binding proteins, thereby suppressing a multi-system degenerative phenotype resembling premature aging.
The threonine kinase controls maternal mRNA translation phosphorylate components of the translational machinery, including translational repressors, which appear to inactivate to promote the oocyte-to-embryo transition.
Hybridization and introgression blur species boundaries and broaden genetic diversity available for adaptation; and widespread introgression underpins the evolution of races of the generalist pathogen Albugo candida that specialise on different host plant species.
Defense-related selective autophagy mediated by the antimicrobial autophagy cargo receptor NBR1/Joka2 is diverted to pathogen penetration sites to restrict plant colonization by the oomycete pathogen Phytophthora infestans.
