Coordinating plant growth and stress resistance via N-terminal protein acetylation
Plant Science Research WeeklyThe mechanisms by which plants switch between growth and stress survival remain somewhat enigmatic. Following on from previous studies, Gong et al. revealed that the conserved N-terminal acetyltransferase B (NatB) helps regulate this balance. Arabidopsis mutants lacking the catalytic subunit of NatB,…
Chloroplast proteostasis prevents aggregation of Huntington’s disease-causing human polyQ protein
Plant Science Research WeeklyCertain human neurodegenerative disorders are caused by aggregation of disordered proteins. In particular, Huntington’s disease is caused by aggregation of a protein called huntingtin, which contains long stretches of glutamine (Q). Llama et al. observed that proteins with long stretches of glutamine…
