چکیده انگلیسی
14-3-3 proteins regulate numerous cellular processes through interaction with their target proteins in a phosphorylation dependent manner. Although proteins that are regulated by 14-3-3s have been studied, the regulatory mechanism of 14-3-3s is poorly understood. In the present study, F-box proteins, a component of Skp1-Cullin-F-box E3 ubiquitin ligase, were identified as 14-3-3 targets using yeast two-hybrid screening. Among them, AtSKIP18 and AtSKIP31, were shown to mediate the degradation of Arabidopsis 14-3-3s. Mutational analyses of AtSKIP18 and AtSKIP31 indicated that the phosphorylation of AtSKIPs is critical for interaction and degradation of 14-3-3s. The loss-of-function mutation in AtSKIP31 resulted in enhanced primary root growth under nitrogen deficient conditions. These findings suggest that AtSKIP31 regulates the primary root growth in nitrogen deficiency via degrading 14-3-3s.
