Specificity / Sensitivity

YAP (D8H1X) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate) recognizes endogenous levels of total YAP protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the carboxy terminus of human YAP protein. The epitope corresponds to a region surrounding Pro435 of human YAP isoform 1. This sequence region is 100% conserved among all known isoforms of human YAP protein.


This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometric analysis in human cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated YAP (D8H1X) XP® Rabbit mAb #14074.



Confocal immunofluorescent analysis of high confluence MCF 10A (left), low confluence MCF 10A (center), and YAP negative RL-7 cells (right) using YAP (D8H1X) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate) (green). Blue pseudocolor in lower images = DRAQ5® #4084 (fluorescent DNA dye). Increased nuclear localization of YAP protein is seen in low confluence (proliferating) cells.

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). 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. Upon phosphorylation at Ser127 by LATS1/2 kinases, YAP translocates to the cytoplasm, where it is sequestered through association with 14-3-3 proteins in an Akt-dependent manner (7-9).
