Erythropoietin (EPO) mediates the growth and differentiation of erythroid progenitors through its interaction with a specific receptor. Using a partial cDNA clone for the murine erythropoietin receptor, we isolated a human genomic clone containing the erythropoietin receptor gene. The coding region of the human EPO receptor gene is contained within eight exons spanning approximately 6 kb. The human gene has a great deal of structural similarity and sequence homology with the murine gene. The murine gene also has eight exons, although the size of each intron is somewhat different. The locations at which the introns interrupt the coding sequence are conserved precisely. The genomic organization of the EPO receptor gene is also shown to be homologous to the genomic organization of the IL-2 receptor beta chain gene. The sequence of 1.1 kb of 5' flanking DNA was characterized and contains consensus sequences for both Sp1 and GATA-1 binding sites and an initiator (Inr)-like element, but lacks both a canonical TATA box and the CACCC consensus sequence found in the murine gene.

Interleukin-15 (IL-15) is a novel cytokine whose effects on T-cell activation and proliferation are similar to those of interleukin-2 (IL-2), presumably because IL-15 utilizes the beta and gamma chains of the IL-2 receptor. Murine IL-15 cDNA and genomic clones were isolated and characterized. The murine Il15 gene was found to consist of eight exons spanning at least 34 kb and was localized to the central region of mouse chromosome 8 by interspecific backcross analysis. Intron positions in a partial human IL15 genomic clone were identical with positions of corresponding introns in the murine gene. The human IL15 gene was mapped to human chromosome 4q31 by fluorescence in situ hybridization.

A 4400-bp genomic sequence and a 332-bp truncated cDNA sequence of the interleukin-2 (IL-2) gene of Indian water buffalo (Bubalus bubalis) were amplified by polymerase chain reaction and cloned. The coding sequence of the buffalo IL-2 gene was assembled from the 5' end of the genomic clone and the truncated cDNA clone. This sequence had 98.5% nucleotide identity and 98% amino acid identity with cattle IL-2. Three amino acid substitutions were observed at positions 63, 124 and 135. Comparison of the predicted protein structure of buffalo IL-2 with that of human and cattle IL-2 did not reveal significant differences. The putative amino acids responsible for IL-2 receptor binding were conserved in buffalo, cattle and human IL-2. The amino acid sequence of buffalo IL-2 also showed very high identity with that of other ruminants, indicating functional cross-reactivity.
