Regulator of the Hippo/SWH (Sav/Wts/Hpo) signaling pathway, a signaling pathway that plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein Hippo (hpo), in complex with its regulatory protein Salvador (sav), phosphorylates and activates Warts (wts) in complex with its regulatory protein Mats, which in turn phosphorylates and inactivates the Yorkie (yki) oncoprotein. Schip1 promotes kinase activity of Tao and enhances phosphorylation of hpo by Tao. Interacts with ex; the interaction results in recruitment of Schip1 to the apical cell membrane. Interacts with Tao; the interaction enhances Tao kinase activity. Interacts with Mer. In eye disks of the third instar larvae, expressed in all cells (at protein level). Death during embryonic or early larval stages. Inactivation in adult eyes results in enlarged eyes with irregular bulging on the surface. Belongs to the SCHIP1 family.
