Mouse Interleukin 11, IL-11 ELI

Cytokine that stimulates the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells and induces megakaryocyte maturation resulting in increased platelet production (PubMed: 8913282).

Also promotes the proliferation of hepatocytes in response to liver damage (PubMed: 22253262).

Binding to its receptor formed by IL6ST and either IL11RA1 or IL11RA2 activates a signaling cascade that promotes cell proliferation, also in the context of various cancers (PubMed: 10026196, PubMed: 23948300).

Signaling leads to the activation of intracellular protein kinases and the phosphorylation of STAT3 (PubMed: 23948300, PubMed: 22253262).

The interaction with the membrane-bound IL11RA and IL6ST stimulates 'classic signaling', whereas the binding of IL11 and soluble IL11RA to IL6ST stimulates 'trans-signaling' (By similarity).
