CC -!- FUNCTION: Acts specifically as a negative regulator of skeletal muscle
CC growth. {ECO:0000250|UniProtKB:O08689}.
CC -!- SUBUNIT: Homodimer; disulfide-linked. Interacts with WFIKKN2, leading
CC to inhibit its activity. Interacts with FSTL3.
CC {ECO:0000250|UniProtKB:O08689}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:O08689}.
CC -!- PTM: Synthesized as large precursor molecule that undergoes proteolytic
CC cleavage to generate an N-terminal propeptide and a disulfide linked C-
CC terminal dimer, which is the biologically active molecule. The
CC circulating form consists of a latent complex of the C-terminal dimer
CC and other proteins, including its propeptide, which maintain the C-
CC terminal dimer in a latent, inactive state. Ligand activation requires
CC additional cleavage of the prodomain by a tolloid-like
CC metalloproteinase. {ECO:0000250|UniProtKB:O08689}.
CC -!- SIMILARITY: Belongs to the TGF-beta family. {ECO:0000305}.
