Summary of different type RING domains from Drosophila melanogaster.

Note: Number, the number of different type RING domains of fruit fly, and subcellular means the number of RING proteins respectively located at nucleus, multiple subcellular compartments, membrane proteins and mitochondrion; Orthologs, the number of putative orthologs of different type RING domains between fruit fly and human; Percentage, the percentage of different type RING domains; Accuracy: the accuracy score of sequence alignments of different type RING domains evaluated using structural information; ID, the average percentage of sequence identity within different type RING domains of fruit fly and the solved RING domains.
