YAP is a transcriptional regulator which can act both as a coactivator and a corepressor and is the critical downstream regulatory target in the Hippo signaling pathway that plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein STK3/MST2 and STK4/MST1, in complex with its regulatory protein SAV1, phosphorylates and activates LATS1/2 in complex with its regulatory protein MOB1, which in turn phosphorylates and inactivates YAP1 oncoprotein and WWTR1/TAZ. Plays a key role to control cell proliferation in response to cell contact. Phosphorylation of YAP1 by LATS1/2 inhibits its translocation into the nucleus to regulate cellular genes important for cell proliferation, cell death, and cell migration. [UniProt]

Titration of the YAP antibody may be required due to differences in protocols and secondary/substrate sensitivity.

A portion of amino acids 420-446 from human YAP1 was used as the immunogen for this YAP antibody.

Aliquot the YAP antibody and store frozen at -20oC or colder.Avoid repeated freeze-thaw cycles.
