Post-translational Modification

Forms a heterodimer with either inhibin alpha chain (forming inhibin A) or inhibin beta-B (forming activin AB). The third form of the active peptide is a homodimer of two beta-A chains forming activin-A. Interchain disulphide bond formation between cysteine residues at position 80. Disulphide bonds between cysteine residues at positions 4 and 12; 11 and 81, 40 and 113, and 44 and 115
