RT   "Cloning of a cDNA encoding the luteinizing hormone beta chain precursor in
RT   the marsupial, Monodelphis domestica.";
RL   Submitted (SEP-2001) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Promotes spermatogenesis and ovulation by stimulating the
CC       testes and ovaries to synthesize steroids. {ECO:0000250}.
CC   -!- SUBUNIT: Heterodimer of a common alpha chain and a unique beta chain
CC       which confers biological specificity to thyrotropin, lutropin,
CC       follitropin and gonadotropin. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- SIMILARITY: Belongs to the glycoprotein hormones subunit beta family.
CC       {ECO:0000305}.
