  1. a In each class, DIR genes involved in segmental duplication (SD) and tandem duplication (TD) were counted. b In each class, the properties of DIR proteins including molecular weight (MW), isoelectric point (pI), and the number of putative N-glycosylation sites (N-gly) were investigated, and the median values were displayed
