Gene Details:

• MSU gene ID: LOC_Os01g16090
• RAPdb gene ID: Os01g0265800
• Gene Symbol: RBP-P
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Overall, our data demonstrate the significant roles of RBP-P in glutelin and prolamine mRNA localization and in the regulation of genes important for plant growth and development through its RNA binding activity and cooperative regulation with interacting proteins.
• In addition, partial loss of RBP-P function conferred a broad phenotypic variation ranging from dwarfism, chlorophyll deficiency and sterility to late flowering and low spikelet fertility.
• Transcriptome analysis highlighted the essential role of RBP-P in regulating storage protein genes and several essential biological processes during grain development.
• RNA-binding protein RBP-P is required for glutelin and prolamine mRNA localization in rice endosperm cells.
• Different mutant RBP-P proteins exhibited varying degrees of reduced RNA binding and/or protein-protein interaction properties, which may account for the mis-localization of storage protein RNAs.
• RNA-binding protein RBP-P binds to both glutelin and prolamine mRNAs, suggesting a role in some aspect of their RNA metabolism.
• Here, we show that rice lines expressing mutant RBP-P mis-localize both glutelin and prolamine mRNAs.
