AR schematic diagrams. A, full-length human AR amino acid
residues 1–919 contain the NH2-terminal domain (NTD)
with activation function-1 (AF1) and Ser-515, DNA binding domain
(DBD) with Ser-578, and ligand binding domain (LBD) with
activation domain-2 (AF2). B, ARNH2-terminal and
DNA binding domain residues 514–627 showing the two zinc modules with
highlighted AR phosphorylation sites Ser-515 and Ser-578. C,
structure of the AR DNA binding domain dimer (green) bound to
androgen response element DNA (orange and blue)
(52) with space-filled Ser-578
indicated with red arrows.
