YAP1 (Transcriptional coactivator YAP1) is a protein that switches other genes on and off. The public catalogues list it as a drug target and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Oesophageal cancer and Breast cancer. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Transcriptional regulator with dual roles as a coactivator and corepressor. Critical downstream regulatory target in the Hippo signalling pathway, crucial for organ size control and tumour suppression by restricting proliferation and promoting apoptosis. The Hippo signalling pathway core involves a kinase cascade featuring STK3/MST2 and STK4/MST1, along with its regulatory partner SAV1, which phosphorylates and activates LATS1/2 in complex with their regulatory protein, MOB1. This activation leads to the phosphorylation and inactivation of the YAP1 oncoprotein and WWTR1/TAZ. Phosphorylation of YAP1 by LATS1/2 prevents its nuclear translocation, thereby regulating the expression of its target genes. The transcriptional regulation of gene expression requires TEAD transcription factors and modulates cell growth, anchorage-independent growth, and induction of epithelial-mesenchymal transition (EMT). Location: Cytoplasm; Nucleus; Cell junction, tight junction; Cell membrane (UniProt). Locus 11q22.1 (HGNC).
