Disclosed are concatameric proteins comprising two soluble domains, in which the C-terminus of a soluble domain of a biologically active protein is linked to the N-terminus of an identical soluble domain or a distinct soluble domain of a biologically active protein. Also, the present invention disclosed dimeric proteins formed by formation of intermolecular disulfide bonds at the hinge region of two monomeric proteins formed by linkage of a concatamer of two identical soluble extracellular regions of proteins involving immune response to an Fc fragment of an immunoglobulin molecule, their glycosylated proteins, DNA constructs encoding the monomeric proteins, recombinant expression plasmids containing the DNA constructs, host cells transformed or transfected with the recombinant expression plasmids, and a method of preparing the dimeric proteins by culturing the host cells. Further, the present invention disclosed pharmaceutical or diagnostic compositions comprising the dimeric protein or its glycosylated form.

L'invention concerne des protéines concatamériques comprenant deux domaines solubles, la terminaison C d'un domaine soluble d'une protéine biologiquement active étant liée à la terminaison N d'un domaine soluble identique ou d'un domaine soluble distinct d'une protéine biologiquement active. Par ailleurs, la présente invention concerne des protéines dimériques formées par formation de liaisons disulfures intermoléculaires au niveau de la zone d'articulation de deux protéines monomériques formées par liaison d'un concatamère de deux zones extracellulaires solubles identiques de protéines impliquant une réponse immunitaire à un fragment Fc d'une molécule d'immunoglobuline, leurs protéines glycosylées, des constructions d'ADN codant pour ces protéines monomériques, des plasmides d'expression recombinés contenant ces constructions d'ADN, des cellules hôtes transformées ou transfectées au moyen de ces plasmides d'expression recombinés, ainsi qu'une méthode de préparation de ces protéines dimériques par culture de cellules hôtes. La présente invention se rapporte en outre à des compositions diagnostiques ou pharmaceutiques comprenant une protéine dimérique ou sa forme glycosylée.
