Activin can be said to be a protein complex that helps in secretion, FSH biosynthesis, and modulation of menstrual cycle. Being dimeric in structure, Activin A is used for increasing level of expression of collagen-type 1 and helps in activation of fibroblasts. As a member of TFG beta family of proteins, there are a number of types of cells, throughout the level of development. It acts as a homodimer to dual beta chains and is only activated when N terminal propeptide is cleaved from each of them. Quite like mouse, rat or other feline creatures, this too has 100% amino acids within itself.

This can be well traced with research done with help of Mouse Activin A Elisa Kit in present times. Quite in unfortunate terms, Activin A has been said to be involved in growth and proliferation of cancers and tumours of the ovarian section. As primary function, Activin A is used for cell proliferation, metabolism, homeostasis, wound repairing, endocrine functioning, and apoptosis. In general cases, when skin is harmed, collagen growth is promoted by proteins to help in healing of wounds. This also helps in maintaining skin layers in best manner. This mediates through complicated trans membrane receptor and shows a series of biological effects and changes secretion levels of hormones. Such a report has been tested and derived in case of ageing process of mice.
