Abstract:
Radiation hybrid mapping assigned the zebrafish [Pro(2)]somatostatin-14 (also termed somatostatin 2; SS2) gene to linkage group 23 of the zebrafish genome, close to the marker nadl1.2. Comparative genomic analysis revealed conserved syntenies of the SS2 gene locus with part of the human 1p36 region, where the cortistatin gene is located. This observation strongly suggests that the SS2 gene in nonmammalian species and the cortistatin gene in mammals are orthologous.
