Phosphothreonine 218 is required for the function of SR45.1 in regulating flower petal development in Arabidopsis.

Plant signaling & behavior - 1 Jan 2014

Zhang Xiao-Ning, Mo Cecilia, Garrett Wesley M, Cooper Bret

Abstract excerpt

RNA splicing is crucial to the production of mature mRNAs (mRNA). In Arabidopsis thaliana, the protein Arginine/Serine-rich 45 (SR45) acts as an RNA splicing activator and initiates the spliceosome assembly. SR45 is alternatively spliced into 2 isoforms. Isoform 1 (SR45.1) plays an important role in the flower petal development whereas isoform 2 (SR45.2) is important for root growth. In this study, we used...
