LATS1 K751 acetylation blocks activation of Hippo signalling and switches LATS1 from a tumor suppressor to an oncoprotein. (PubMed, Sci China Life Sci)
Functionally, LATS1-K751Q, the acetylation mimic mutant potentiated lung cancer cell migration, invasion and tumor growth, whereas LATS1-K751R, the acetylation deficient mutant inhibited these functions. Taken together, we demonstrated a previously unidentified post-translational modification of LATS1 that converts LATS1 from a tumor suppressor to a tumor promoter by suppression of Hippo signalling through acetylation of LATS1.
