Abstract

Immunocytochemistry enables determination of cellular localization and relative abundance of proteins. This protocol describes a rapid and cost-effective approach to study the cellular localization of YAP (and TAZ), the transcriptional co activators of the Hippo pathway, in mammalian cells. Cells are seeded onto coated cover slips, cultivated and treated as required. Subsequently, they are chemically fixed, and cellular proteins are fluorescently labeled by means of specific antibodies. Multiplexing antibodies enables ascertaining the subcellular localization of YAP and TAZ and thereby also the activation state of the Hippo pathway in various cell types.
