WebbY915 is one of the androgen receptor residues that affect ligand binding , and Y915S is causative of AIS [23,24]. Our bioinformatics analysis identified the Y915S mutation and phosphorylation of Y915 by Src kinases [31,67]. In fact, when the androgen receptor is tyrosine-phosphorylated, it is activated in an androgen-independent manner.
