Phospho-YAP (Ser127) Antibody

4911:

IHC / Paraffin , Western Blotting

Phospho-YAP (Ser127) Antibody detects endogenous levels of YAP only when phosphorylated at serine 127.

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser127 of human YAP. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western blot analysis of extracts from MDA-MB-468 cells, untreated or treated with wortmannin and LY294002, using Phospho-YAP (Ser127) Antibody. The phospho-specificity of the antibody was verified by treating the membrane with (+) or without (-) calf intestinal phosphatase (CIP) after western transfer.

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human colon carcinoma, showing cytoplasmic and nuclear localization, using Phospho-YAP (Ser127) Antibody.

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human lung carcinoma control (left) or lambda phosphatase-treated (right), using Phospho-YAP (Ser127) Antibody

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human breast carcinoma, using Phospho-YAP (Ser127) Antibody in the presence of control peptide (left) or antigen specific peptide (right).

YAP (Yes-associated protein, YAP65) was identified based on its ability to associate with the SH3 domain of Yes. It also binds to other SH3 domain-containing proteins such as Nck, Crk, Src, and Abl (1). In addition to the SH3 binding motif, YAP contains a PDZ interaction motif, a coiled-coil domain, and WW domains (2-4). While initial studies of YAP all pointed towards a role in anchoring and targeting to specific subcellular compartments, subsequent studies showed that YAP is a transcriptional co-activator by virtue of its WW domain interacting with the PY motif (PPxY) of the transcription factor PEBP2 and other transcription factors (5,6). Upon phosphorylation at Ser127, YAP interacts with 14-3-3 in an Akt-dependent manner and suppresses p73-mediated apoptosis (6).
