We isolated the four cDNA encoding proteins, similar to human SUMOs, from the medaka fish, Oryzias latipes: OlSUMO-1, OlSUMO-2, OlSUMO-3, and OlSUMO-4. The amino acid sequences of OlSUMO-2, OlSUMO-3 and OlSUMO-4 are 89‒94% identical, but they share only 45% identity with OlSUMO-1. Phylogenetic analysis, transient expression of OlSUMOs in cultured cells and in vitro binding of OlSUMOs with two different SUMO-interacting proteins demonstrated that the medaka SUMO paralogs can be grouped into two subfamilies, OlSUMO-1 and OlSUMO-2/3/4, respectively. Furthermore, this is the first report of all four OlSUMO transcripts being expressed in medaka embryos, implying that they have a role in fish development. The study will improve understanding of the relationship between structural and functional diversity of SUMO paralogs during vertebrate evolution., http://www.springerlink.com/content/p7h80l28340t5271/}, pages = {737--750}, title = {Identification of four sumo paralogs in the medaka fish, oryzias latipes, and their classification into two subfamilies}, volume = {48}, year = {2010}, yomi = {サイトウ, ヒサト and キタノ, タケシ and サイトウ, ヒサト} }
