CC   -!- FUNCTION: Shared alpha chain of the active heterodimeric glycoprotein
CC       hormones thyrotropin/thyroid stimulating hormone/TSH,
CC       lutropin/luteinizing hormone/LH and follitropin/follicle stimulating
CC       hormone/FSH. These hormones bind specific receptors on target cells
CC       that in turn activate downstream signaling pathways.
CC       {ECO:0000250|UniProtKB:P01215}.
CC   -!- SUBUNIT: Heterodimer. The active hormones thyrotropin, lutropin and
CC       follitropin are heterodimers composed of CGA, a common alpha chain
CC       described here and a unique beta chain which confers their biological
CC       specificity to the hormones: TSHB for thyrotropin, LHB for lutropin and
CC       FSHB for follitropin. {ECO:0000250|UniProtKB:P01215}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P01215}.
CC   -!- SIMILARITY: Belongs to the glycoprotein hormones subunit alpha family.
CC       {ECO:0000305}.
