Growth differentiation factor 11 (GDF11) also known as bone morphogenetic protein 11 (BMP-11) is a protein that in humans is encoded by the GDF11 gene.
It acts as a cytokine.
The BMP group of proteins is characterized by a polybasic proteolytic processing site, which is cleaved to produce a protein containing seven conserved cysteine residues. GDF11 is a myostatin-homologous protein that acts as an inhibitor of nerve tissue growth. GDF11 has been shown to suppress neurogenesis through a pathway similar to that of myostatin, including stopping the progenitor cell-cycle during G-phase. The similarities between GDF11 and myostatin imply a likelihood that the same regulatory mechanisms are used to control tissue size during both muscular and neural development.
