Function

Madiator in the activation of TGF-尾 sig ling pathway and controls cilia length (25959824). Downstream of TGFBR1 and 2, which phosphorylate SMAD2/3 at base of cilium upon TGF-尾 stimulation (23746451).

Model organism evidence

Danio rerio (1 reference)

Additionally, we found that Kupffer's vesicle formation and ciliogenesis were impaired following gdf11 deletion.

Mus musculus (1 reference)

Primary cilia abnormalities participate in the occurrence of spontaneous abortion through TGF-β/SMAD2/3 signaling pathway.
