MOB1A is a component of the Hippo signaling pathway, which controls organ size and tumor growth by enhancing apoptosis. MOB1A protein plays a crucial role in cell cycle regulation and tumor suppression, functioning as a key component of the Hippo signaling pathway, which is essential for controlling cell growth and preventing excessive cell proliferation. This pathway is particularly important in maintaining tissue homeostasis and preventing cancer development, as MOB1A regulates the activity of downstream effectors like NDR-family protein kinases and LATS1 kinase. Through binding and modulating these kinases, MOB1A helps orchestrate cellular responses to various stimuli, including stress and growth factors, thereby influencing cell fate decisions.
