We report a novel gene Peas that constitutes an overlapping gene complex in mammalian genome. We have cloned human and mouse Peas cDNAs (hPEAS/mPeas) and analyzed their tissue and stage-specific expressions. Peas protein contains six repeated kelch motifs, structurally similar to RAG2, a V(D)J recombination activator, and is evolutionarily conserved among mammals, birds, insects, and nematodes. Northern, RNA in situ hybridization and immunohistochemical analyses showed that mPeas is specifically transcribed in testis, particularly in pachytene spermatocytes in which it is localized to the cytoplasm and meiotic chromatin. It is suggested that Peas may be involved in meiotic recombination process. (C) 2003 Federation of European Biochemical Societies. Published by Elsevier Science B.V. All rights reserved.
