The scaffold protein RACK1 regulates root growth and gravitropic response by recruiting PINOID to phosphorylate the auxin efflux transporter PIN-FORMED2
{{output}}
The scaffolding protein RACK1 is involved in polar auxin transport and signaling. It binds to PINOID and PIN-FORMED2, enhancing their interaction and phosphorylation-dependent auxin efflux. Knocking down RACK1 genes impairs auxin-related processes such as root... ...
