RL Ann. Hum. Genet. 71:18-28(2007).
CC -!- FUNCTION: Together with the alpha chain CGA constitutes follitropin,
CC the follicle-stimulating hormone, and provides its biological
CC specificity to the hormone heterodimer. Binds FSHR, a G protein-coupled
CC receptor, on target cells to activate downstream signaling pathways.
CC Follitropin is involved in follicle development and spermatogenesis in
CC reproductive organs. {ECO:0000250|UniProtKB:P01225}.
CC -!- SUBUNIT: Heterodimer. The active follitropin is a heterodimer composed
CC of an alpha chain/CGA shared with other hormones and a unique beta
CC chain/FSHB shown here. {ECO:0000250|UniProtKB:P01225}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P01225}.
CC Note=Efficient secretion requires dimerization with CGA.
CC {ECO:0000250|UniProtKB:P01225}.
CC -!- SIMILARITY: Belongs to the glycoprotein hormones subunit beta family.
CC {ECO:0000305}.
