An extended ubiquitin of Dictyostelium is located in the small ribosomal subunit.

Abstract

According to its cDNA sequence, the product of the DUB1 gene of Dictyostelium discoideum, called ubex52, consists of a ubiquitin monomer with a basic COOH-terminal tail of 52 amino acids that includes a putative zinc finger motif. Antipeptide antibodies raised against the COOH-terminal end of the tail indicated that the ubex52 protein is present in all… (More)
