[Term] id: PR:000000637 name: activin/inhibin beta A chain isoform 1 cleaved 1 def: "An activin/inhibin beta A chain isoform 1, signal peptide removed form that has been processed by subsequent removal of the propeptide, yielding the mature protein. It is a subunit of inhibin A and activin A complexes. Inhibin A complex is a dimer of INHA and INHBA, whereas activin A complex is a homodimer of INHBA."
