Western blot analysis of extracts from HeLa cells (lane 1) or YAP knock-out cells (lane 2) using Phospho-YAP (Ser127) Antibody #4911 (upper), and GAPDH (D6H11) XP® Rabbit mAb #5174 (lower). The absence of signal in the YAP knock-out HeLa cells confirms specificity of the antibody for YAP.
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.

Protocol Id: 10
Phospho-YAP (Ser127) Antibody detects endogenous levels of YAP only when phosphorylated at serine 127. This antibody may cross-react with phospho-TAZ (Ser89).
Human, Mouse, Rat
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.
YAP (Yes-associated protein, YAP65) was first 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). In its capacity as a transcriptional co-activator, YAP is now widely recognized as a central mediator of the Hippo Pathway, which plays a fundamental and widely conserved role in regulating tissue growth and organ size (6-8). Phosphorylation at multiple sites (e.g., Ser109, Ser127) by LATS kinases promotes YAP translocation from the nucleus to the cytoplasm, where it is sequestered through association with 14-3-3 proteins (7-9). These LATS-driven phosphorylation events serve to prime YAP for subsequent phosphorylation by CK1δ/ε in an adjacent phosphodegron, triggering proteasomal degradation of YAP (10).
