Synteny and phylogenetic analysis of paralogous thyrostimulin beta subunits (GpB5) in vertebrates.
At some point early in the vertebrate lineage, two whole genome duplication events (1R, 2R) took place that jacques marie mage baudelaire 2 allowed for the diversification and sub-/neo-functionalization of the glycoprotein hormones (GpHs).All jawed vertebrates possess the GpHs luteinizing hormone (LH), follicle stimulating hormone (FSH), and thyroi
