Concerted evolution in protists: recent homogenization of a polyubiquitin gene in Trichomonas vaginalis.

Journal of molecular evolution - 1 Nov 1995

Keeling P J, Doolittle W F

Abstract excerpt

Ubiquitin is a 76-amino-acid protein with a remarkably high degree of conservation between all known sequences. Ubiquitin genes are almost always multicopy in eukaryotes, and often are found as polyubiquitin genes--fused tandem repeats which are coexpressed. Seventeen ubiquitin sequences from the amitochondrial protist Trichomonas vaginalis have been examined here, including an 11-repeat fragment of a...
