Abstract

With the development of high-throughput sequencing technologies, sequence data is collected at a high rate and their functional annotation remains a major challenge. The ATXN2 gene encodes a protein with an unknown function in rice (Oryza sativa). The aim of this study was to determine the structure of the domain and predict the function of this protein. So the sequence motif phylogenetic tree with 164 ATAXIN-2 amino acid sequences from 45 plant species was analyzed by MEME Suite and Phylip software. The results revealed two general classes of ATAXIN-2 proteins. The absence of the LsmAD domain in one class may confer distinct functional characteristics compared to another ATAXIN-2 class. In this study, the function of ATAXIN-2 was found to be RNA binding protein that plays a role in the regulation of cytoplasmic mRNA in rice embryogenesis. Findings from this study could be the basis for research on the function of this protein in targeting separate subsets of mRNA to subcellular locations in plants, which are recruited by embryonic bipolar cells to establish specific functional compartments.
