General description

Phosphorylation plays an important role in regulating protein activities and various cellular signaling events. Posttranslational phosphorylation can occur on histidine (pHis), serine (pSer), threonine (pThr), and tyrosine (pTyr) residues. Due to the early advent of anti-pTyr antibodies, tyrosine phosphorylation remains the mostly studied signaling events in all biological research fields. Tyrosine phosphorylation is considered to be one of the key steps in signal transduction and regulation of enzymatic activity. Before the availability of anti-pTyr antibodies, protein tyrosine phosphorylation was routiniely detected by time-consuming radioactive labeling. Although radioactive labeling is still considered as more sensitive, advancement in detection technology has greatly improved the detection limits of antibody-based methods. Anti-pTyr antibodies are commonly used in ELISA, immunoprecipitation, immunoblotting (including dot blot and Western blot), as well as indirect immunofluourescent detection of tyrosine phosphorylation in tissue and cell samples.
