IPP-2 (phospho Ser120/S121) Rabbit Polyclonal Antibody

Protein phosphatase-1 (PP1) is one of the main eukaryotic serine/threonine phosphatases. The protein encoded by this gene binds to the catalytic subunit of PP1, strongly inhibiting its activity. Ten related pseudogenes have been found throughout the human genome. Several splice variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015], function:Inhibitor of protein-phosphatase 1., PTM:Phosphorylation on Thr-73 by GSK3 activates PP1 by dissociating the PP1-PPP1R2 complex (By similarity) . Phosphorylation on Ser-44 by ATM activates PP1 by dissociating the PP1-PPP1R2 complex., similarity:Belongs to the protein phosphatase inhibitor 2 family., subunit:Heterodimer with PP1.
