Popis: In Drosophila, the RING finger protein d-Goliath was originally identified as a transcription factor involved in the embryo mesoderm formation [Bouchard, M.L., Cote, S., 1993. The Drosophila melanogaster developmental gene g1 encodes a variant zinc-finger-motif protein. Gene 125, 205-209]. In mouse, the m-Goliath mRNA level was shown to be increased in growth factor withdrawal-induced apoptosis of myeloid cells [Baker, S.J., Reddy, E.P., 2000. Cloning of murine G1RP, a novel gene related to Drosophila melanogaster g1. Gene 248, 33-40]. Due to its putative function of transcription factor in apoptosis, we cloned the human cDNA for h-Goliath and characterized the expression of the protein in blood and bone marrow cells. The human protein of 419 aa (44 kDa) contains a protease-associated domain, a transmembrane domain and a RING-H2 motif. This structure classifies h-Goliath as a new member of a human family of ubiquitin ligases with GRAIL (gene related to anergy in lymphocytes) as founder. This E3 ligase controls the development of T cell clonal anergy by ubiquitination [Anandasabapathy, N., Ford, G.S., Bloom, D., Holness, C., Paragas, V., Seroogy, C., Skrenta, H., Hollenhorst, M., Fathman, C.G., Soares, L., 2003. GRAIL: an E3 ubiquitin ligase that inhibits cytokine gene transcription is expressed in anergic CD4+ T cells. Immunity 18, 535-547]. In vitro ubiquitination studies support the E3 ubiquitin ligase activity of h-Goliath. In human, the protein is expressed under 3 isoforms, a major one at 28 kDa and two others at 46 and 55 kDa. These proteins come from a common precursor (44 kDa) as we observed using in vitro transcription-translation. Using immunohistochemistry on blood or bone marrow smears, of healthy or leukemia samples, we found that the protein expression was restricted to the cytoplasm of progenitors and fully differentiated leukocyte populations. We did not observe any modification of h-Goliath expression or localization in leukemia. In these cells, this new E3 ubiquitin ligase protein does not seem associated with a differentiation state of the cell or with apoptosis.
