Description

YAP1 serves as a critical transcriptional coactivator in the Hippo signaling pathway, where its activity is tightly regulated through phosphorylation. Phosphorylation at serine 127 represents a key regulatory event that promotes cytoplasmic retention of YAP1 through 14-3-3 protein binding, effectively suppressing its transcriptional activity. This phosphorylation site has become essential for researchers investigating Hippo pathway dynamics, organ size control, and the dysregulation of YAP1 signaling frequently observed in cancer progression.

This recombinant monoclonal antibody, generated against a synthetic phosphopeptide corresponding to human Phospho-YAP1 at S127, offers the consistency and reproducibility that phospho-specific detection demands. Because recombinant antibodies are produced from a defined sequence, researchers can expect reliable lot-to-lot performance, which is particularly valuable when tracking subtle changes in phosphorylation status across experimental conditions. The rabbit IgG format and affinity-chromatography purification ensure high specificity for this critical phospho-epitope.

Validation studies demonstrate robust performance across multiple applications. Western blot analysis in HepG2 whole cell lysates, with and without Calyculin A treatment, confirms detection of the expected 65 kDa band, providing researchers with a reliable system for monitoring phosphatase-dependent regulation of YAP1. Immunohistochemistry validation in paraffin-embedded human endometrial cancer tissue further extends the antibody's utility for studying YAP1 phosphorylation in clinical specimens and tissue-based research contexts.

For investigators exploring signal transduction mechanisms, particularly those examining how upstream kinases and phosphatases modulate YAP1 localization and activity, this antibody provides a dependable tool for dissecting Hippo pathway regulation in human samples.

Target Background

Function

Transcriptional regulator which can act both as a coactivator and a corepressor and is the critical downstream regulatory target in the Hippo 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 STK3/MST2 and STK4/MST1, in complex with its regulatory protein SAV1, phosphorylates and activates LATS1/2 in complex with its regulatory protein MOB1, which in turn phosphorylates and inactivates YAP1 oncoprotein and WWTR1/TAZ. Plays a key role in tissue tension and 3D tissue shape by regulating cortical actomyosin network formation. Acts via ARHGAP18, a Rho GTPase activating protein that suppresses F-actin polymerization. Plays a key role in controlling cell proliferation in response to cell contact. Phosphorylation of YAP1 by LATS1/2 inhibits its translocation into the nucleus to regulate cellular genes important for cell proliferation, cell death, and cell migration. The presence of TEAD transcription factors are required for it to stimulate gene expression, cell growth, anchorage-independent growth, and epithelial mesenchymal transition (EMT) induction. Suppresses ciliogenesis via acting as a transcriptional corepressor of the TEAD4 target genes AURKA and PLK1. In conjunction with WWTR1, involved in the regulation of TGFB1-dependent SMAD2 and SMAD3 nuclear accumulation.; Activates the C-terminal fragment (CTF) of ERBB4 (isoform 3).; Activates the C-terminal fragment (CTF) of ERBB4 (isoform 3).
