General description

Monoclonal Anti-phospho-YAP1 (pTyr357) (mouse IgM isotype) is derived from the hybridoma PYP-76 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic phosphopeptide corresponding to a fragment containing (pTyr357) of human YAP1 conjugated to KLH. Yes-associated protein 1 (YAP1) is a modular adapter protein with multiple protein interaction domains that was originally identified based on its interaction with the Src-family tyrosine kinase c-Yes. YAP1 contains a proline-rich amino terminus, a WW domain, a coiled-coil and a PDZ-binding motif at the extreme C-terminus.


Anti-phospho-YAP1 (pTyr357) antibody, Mouse monoclonal has been used in
  • immunoblotting
  • enzyme linked immunosorbent assay (ELISA)
  • immunofluorescence

Biochem/physiol Actions

YAP1 has been shown to stabilize p73 by preventing Itch-mediated ubiquitination of p73.
YAP1 is a WW domain containing protein that is known to associate with a wide range of transcription factors and functions as a transcriptional co-activator. It may also regulate p73 gene function in response to DNA damage. Alterations in YAP1 have been associated with tumor development

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Epidermal growth factor receptor (EGFR) mutations are found in lung adenocarcinomas leading to tumor cells proliferation and survival. EGFR tyrosine kinase inhibitors (TKIs) that block EGFR activity are effective therapeutics for EGFR-mutant lung adenocarcinoma patients, but TKI-resistance inevitably occurs. The...

Yes-associated protein (YAP) is a transcriptional coactivator that promotes cell proliferation, stem cell maintenance and tissue homeostasis. The YAP activity is primarily regulated through an inhibitory phosphorylation by the serine/threonine kinases of Hippo pathway. Here, we show that receptor tyrosine...

The mechanisms that regulate mammalian organ size are poorly understood. It is unclear whether the pathways that control organ size also impinge on stem/progenitor cells. A highly expressed gene in stem cells is YAP1, the ortholog of Drosophila Yorkie, a...
