CC   -!- FUNCTION: Relaxin is an ovarian hormone that acts with estrogen to
CC       produce dilatation of the birth canal in many mammals. It bears mature
CC       young, and allows separation of the pelvic bones.
CC   -!- SUBUNIT: Heterodimer of a B chain and an A chain linked by two
CC       disulfide bonds.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed in the endometrium during pregnancy and
CC       in mammary gland during lactation.
CC   -!- SIMILARITY: Belongs to the insulin family. {ECO:0000305}.
