Protein
Glycoprotein hormones alpha chain
Gene
CGA
Organism
Trichosurus vulpecula (Brush-tailed possum)
Status
Functioni
Shared alpha chain of the active heterodimeric glycoprotein hormones thyrotropin/thyroid stimulating hormone/TSH, lutropin/luteinizing hormone/LH and follitropin/follicle stimulating hormone/FSH. These hormones bind specific receptors on target cells that in turn activate downstream signaling pathways.By similarity

Interactioni
Subunit structurei
Heterodimer. The active hormones thyrotropin, lutropin and follitropin are heterodimers composed of CGA, a common alpha chain described here and a unique beta chain which confers their biological specificity to the hormones: TSHB for thyrotropin, LHB for lutropin and FSHB for follitropin.
