| Name | activin A complex |
| ID | GO_0043509 |
| collection_id | Cellular component |
| Alternative ID | GO:0048181 |
| Description | A nonsteroidal regulator, composed of two covalently linked inhibin beta-A subunits (sometimes known as activin beta-A or activin/inhibin beta-A). |
| Comment | Note that the actions of the activin complex are the opposite of those of the inhibin complex, which is a dimer of an inhibin beta-A or inhibin beta-B subunit and an inhibin alpha subunit. See also the cellular component term 'inhibin complex ; GO:0043511'. |
