Relaxin-2, also called H2 relaxin, is a peptide hormone that plays an important role in female reproduction. It circulates in the blood as a dimer of disulfide-linked alpha and beta chains. Relaxin is best known as a labor hormone that promotes the growth and softening of the cervix, the development of the mammary glands, and has a pronounced effect on the uterus. In particular, it promotes angiogenesis, inhibits MMP production and activity, and downregulates estrogen receptor alpha expression.
