Tyrosine hydroxylase and insulin-like growth factor II but not insulin are adjacent in the teleost species barramundi, Lates calcarifer.
In humans, the genes encoding tyrosine hydroxylase (TH), insulin and insulin-like growth factor II (IGF-II) form an extremely tight linkage group on chromosome 11p15. Characterisation of the homologous genomic region of a teleost, the barramundi Lates calcarifer, revealed tight linkage of the TH and IGF-II genes, and the absence of the gene encoding insulin.
