In the presence of brassinolide, the activated phosphatase BSU1 dephosphorylates BIN2 and promotes its degradation by the 26S proteasome system, thus blocking its activity. BES1 and BZR1

are then dephosphorylated by PROTEIN PHOSPHATASE2A

(PP2A), and the active forms of BES1 and BZR1 move into the nucleus where they regulate the expression of brassinolide response genes

#Unit 3. Fundamental Processes

pri-miRNA is processed in a two-step reaction

The first step is catalyzed by Drosha, an RNase III superfamily member endonuclease, in the nucleus. Drosha reduces the pri-RNA to about a 70-bp, hairpin-shaped precursor fragment, pre-miRNA

Both Astrocytes

send processes to blood vessels, where they induce capillaries to form the tight junctions making up the blood–brain barrier send processes that envelop synapses and the surface of nerve cells.
