Determining the Phosphorylation Status of Hippo Components YAP and TAZ Using Phos-tag
Protein phosphorylation is one of the most important posttranslational modifications in cell signaling and regulation. Protein phosphorylation can be detected by site-specific phospho-antibodies, but generating these antibodies can be costly, time-consuming, and difficult. Recently, Phos-tag technology has been developed to detect protein phosphorylation. Here, we describe our method for using Phos-tag gels to compare the phosphorylation status of YAP and TAZ, the most important downstream effectors of the Hippo pathway.
