WW domains are the smallest known independently foldable protein structural motifs that are involved in cellular events like protein turnover, splicing, development, and tumor growth control. These motifs bind the polyproline rich ligands. While the WW domains of animal origin are well characterized, the same from plant origin are not well documented yet. Despite the small repertoire of WW proteome of plants (in comparison to animal WW proteome) functional diversity is reported to be equally vivid for plants also. Here, for the first time, we report the structural and functional properties of an Arabidopsis thaliana (At) WW domain containing protein F4JC80 by using homology modeling and docking techniques. Our findings report that the At F4JC80 protein contains two WW domains which bear the standard triple β sheet structure and structurally and functionally resemble Class I WW domains of E3 ubiquitin ligase family but their structural differences impact their polypeptide binding abilities differently.
