Function
function
Inhibins and activins inhibit and activate, respectively, the secretion of follitropin by the pituitary gland. Inhibins/activins are involved in regulating a number of diverse functions such as hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development or bone growth, depending on their subunit composition. Inhibins appear to oppose the functions of activins. Induces somatostatin in the ciliary ganglion neurons and may play a role in regulating neurotransmitter phenotype.

Expression
Tissue specificity
Ciliary ganglion neurons. Levels are higher in the choroid than the iris.
Developmental stage
Levels increase in the iris from embryonic day 9 (9 dpc) to 16 dpc and in the choroid, levels are high from 9 dpc to 14 dpc but drop at 16 dpc.
Interaction
Subunit
Dimeric, linked by one or more disulfide bonds. Inhibin A is a dimer of alpha and beta-A. Inhibin B is a dimer of alpha and beta-B. Activin A is a homodimer of beta-A. Activin B is a homodimer of beta-B. Activin AB is a dimer of beta-A and beta-B.
