What pLDDT means and how to read it

Function

Transcription factor which plays a key role in 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 (PubMed:18258485, PubMed:18313299). 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 (Probable). The Hippo/SWH signaling pathway inhibits the activity of the transcriptional complex formed by Scalloped (sd) and Yki…

Subunit structure

Interacts (via C-terminus) with vg (via Ser-rich sd binding domain); the interaction is direct (PubMed:12702681, PubMed:12782275, PubMed:14526388, PubMed:33060790, PubMed:9799424, PubMed:9869635, PubMed:9869643). Interacts (via C-terminus) with yki (via N-terminus); enhances its transcriptional activity (PubMed:18313299)
