Further observations indicate that Laforin‐macrophage stimulating 1/2 (MST1/2) complexes assemble in glycogen liquid droplets to relieve MST1/2 inhibition on yes‐associated protein (YAP), thereby promoting malignant cell transformation.[194] Transforming growth factor β (TGF‐β) functions as a main agitator of cancer invasion and metastasis. Here, MST1 is linked to cancer.
