synthetic peptide corresponding to amino acids 351-362 (pTyr357) located in the C-terminal region of human YAP1. The sequence is identical in chicken YAP1 and highly conserved in mouse YAP1 (single amino acid substitution).

General description

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
Anti-phospho-YAP1 pTyr357 antibody is specific for human phospho-YAP1 pTyr357. The product may react with chicken and mouse phospho-YAP1 pTyr357. In immunoblotting, staining of the phospho-YAP1 (pTyr357) band is specifically inhibited by the immunizing peptide; but no inhibition is observed with the unmodified peptide.

Physical form

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


Anti-phospho-YAP1 pTyr357 antibody is suitable for use in western blot (0.5-1 μg/mL ) and indirect immunofluorescence (5-10 μg/mL) using HEK-293T cells co-transfected with human YAP1 and human c-Abl.
