Androgen receptor phosphorylation.
Phosphorylation of transcription factors plays an important role in regulation of gene expression. DNA-binding, transactivation activity, and subcellular trafficking of specific transcription factors have been shown to be regulated by phosphorylation/dephosphorylation. Steroid hormone receptors are phospho-proteins, and mutations in phosphorylation sites significantly affect the transactivation capacity of these ligand-dependent transcription factors. At present, it is unknown which amino acid residues of the human androgen receptor are phosphorylated and whether phosphorylation of particular sites is a prerequisite for proper androgen receptor function. The aim of our future research is to map all phosphorylation sites in the human androgen receptor, and to analyze their importance by mutational analysis in vitro and in vivo using a number of functional assays.
