The exon-intron organization and sequences of the exon-intron boundaries of the human gp130 transmembrane receptor gene have been determined using genomic DNAs as samples. The gp130 gene comprises 17 exons and 16 introns. The positions of the exon-intron boundaries show good correlation to the functional/homology regions of gp130. Exons 3-17 code for the gp130 protein, and each subdomain of the receptor is encoded by a set of exons. The coding potential of exons and the intron phasing of the human gp130 gene conform to the patterns observed previously for other cytokine receptor genes. This supports the notions that the gp130 gene evolved from the same ancestral gene that gave rise to other members of the cytokine receptor family. (C) 2000 Elsevier Science B.V. All rights reserved.
