Predicted to enable cytokine activity and type I activin receptor binding activity. Predicted to be involved in several processes, including embryonic cleavage; positive regulation of protein phosphorylation; and transmembrane receptor protein serine/threonine kinase signaling pathway. Predicted to act upstream of or within negative regulation of cell growth and oocyte growth. Predicted to be located in cytoplasm. Predicted to be active in extracellular space. Human ortholog(s) of this gene implicated in primary ovarian insufficiency 14. Orthologous to human GDF9 (growth differentiation factor 9). [provided by Alliance of Genome Resources, Apr 2022]
