PP1[http://www.signaling-gateway.org/update/images/su-0406-3-i1.jpg]has an N-terminal, α/β domain, and a C-terminal β domain.  The β domains come together as a <scene name='User:Iris_To/Retinoblastoma_Protein_Regulation/Rb_cterm_binding/7'>β-sandwich</scene>.  The catalytic site is inside a a large Y-shaped cleft made by the three domains.  Grooves are made by the domains: a hydrophobic, acidic, and C-terminal groove.  <scene name='User:Iris_To/Retinoblastoma_Protein_Regulation/Rb_cterm_binding/2'>Rb binds PP1c with an extended conformation at hydrophobic interface</scene> of the β-sandwich subdomain.
