Anti-YAP1 antibody,Abcam,AB195987

Target data The protein expressed by the YAP1 gene functions as a transcriptional regulator, acting both as a coactivator and corepressor. It is a critical downstream regulatory target in the Hippo signaling pathway, which is crucial for organ size control and tumor suppression, as it restricts proliferation and promotes apoptosis. The pathway involves a kinase cascade where STK3/MST2 and STK4/MST1 activate LATS1/2, which then inactivates the YAP1 oncoprotein. YAP1 plays a key role in tissue tension and 3D tissue shape by regulating cortical actomyosin network formation through ARHGAP18. It controls cell proliferation in response to cell contact, with its phosphorylation by LATS1/2 preventing nuclear translocation necessary for regulating cellular genes linked to proliferation, death, and migration. TEAD transcription factors are needed for YAP1 to stimulate gene expression, cell growth, anchorage-independent growth, and EMT induction. Additionally, YAP1 suppresses ciliogenesis by repressing TEAD4 target genes AURKA and PLK1. Isoforms 2 and 3 of YAP1 activate the C-terminal fragment of ERBB4 (isoform 3).
