function:Inhibitor of PPP1CA and PPP1CC phosphatase activities. Has inhibitory activity on PPP1CA only when phosphorylated. Binds to mRNA, single-stranded DNA (ssDNA), poly(A) and poly(G) homopolymers.,PTM:Phosphorylated on Ser-398 and Thr-400 by PKA within the region necessary for interaction with PPP1CA.,similarity:Contains 1 C3H1-type zinc finger.,similarity:Contains 1 TFIIS N-terminal domain.,subcellular location:Found in discrete nucleoplasmic bodies and within nucleoli.,subunit:Interacts with PPP1CA and PPP1CC.,tissue specificity:Expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.,
Nucleus . Found in discrete nucleoplasmic bodies and within nucleoli. Associates with chromatin during interphase, excluded from condensed chromosomes during early mitosis and is reloaded onto chromosomes at the late telophase (By similarity). .
Expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.
