DEP2

Annotated Information
Function
Mutation
The DEP2 locus was mapped to the long arm of rice chromosome 7. dep2-1:The 31-bp deletion in dep2-1 starts at 2184bp from the initiation codon ATG and caused a frameshift; dep2-2:the G/A substitution in the second intron of dep2-2 caused an altered splicing site of the second intron and also led to a frameshift. LOC_Os07g42410 was considered a candidate for the DEP2 gene.
Expression
DEP2 gene expression in the dividing zones of rachis, branches, and florets was higher than in other parts of the rice plant. This gene is highly expressed in young panicles ranging from 1 to 15 cm in length;low level expression was also detected in the other organs, including roots,stems,leaves and leaf sheathes.
Evolution
DEP2 may be a plant-specific protein. The only existing low similarity to CIP7 in Arabidopsis is found at the N terminal part of the protein, while the COP1-interacting motif, transcription activation domain, and the nuclear localization signal domain are all missing in DEP2.
