Protein attributes

Sequence length	261 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Preferentially catalyzes the dephosphorylation of 'Ser-5' within the tandem 7 residues repeats in the C-terminal domain (CTD) of the largest RNA polymerase II subunit POLR2A. Negatively regulates RNA polymerase II transcription, possibly by controlling the transition from initiation/capping to processive transcript elongation By similarity. Recruited by REST to neuronal genes that contain RE-1 elements, leading to neuronal gene silencing in non-neuronal cells. Ref.3
Catalytic activity	A phosphoprotein + H2O = a protein + phosphate.
Cofactor	Binds 1 magnesium ion per monomer By similarity.
Subunit structure	Monomer By similarity. Interacts with REST By similarity.
Subcellular location	Nucleus By similarity.
Tissue specificity	Expression is restricted to non-neuronal tissues. Ref.3
Sequence similarities	Contains 1 FCP1 homology domain.
