ASPPs multimerize protein phosphatase 1. [PDF]
Protein Phosphatase 1 (PP1) activity is thought to be spatiotemporally defined by hundreds of different regulatory subunits, but their mechanisms of action are largely unknown.

Inhibitor-3 inhibits Protein Phosphatase 1 via a metal binding dynamic protein–protein interaction [PDF]
Protein phosphatase 1 (PP1) is regulated by intrinsically disordered proteins like inhibitor-3, I3. The authors show that I3 does not inhibit PP1 by forming a rigid complex but instead by binding dynamically with its active site metals, showing how ...

Loss of protein phosphatase 1 regulator TIMAP protein triggers EMT in A549 cells [PDF]
Background Epithelial–mesenchymal transition (EMT) is a cellular reprogramming process that enables epithelial cells to acquire mesenchymal traits, leading to enhanced motility, invasiveness, and resistance to therapy.

Mapping the Protein Phosphatase 1 Interactome in Human Cytomegalovirus Infection [PDF]
Protein phosphorylation is a crucial regulatory mechanism in cellular homeostasis. The human cytomegalovirus (HCMV) incorporates protein phosphatase 1 (PP1) into its tegument, yet the biological relevance and mechanisms of this incorporation remain ...

PPP1R2 stimulates protein phosphatase-1 through stabilisation of dynamic subunit interactions [PDF]
Protein Ser/Thr phosphatase PP1 is always associated with one or two regulatory subunits or RIPPOs. One of the earliest evolved RIPPOs is PPP1R2, also known as Inhibitor-2.

SDS22 coordinates the assembly of holoenzymes from nascent protein phosphatase-1 [PDF]
SDS22 forms an inactive complex with nascent protein phosphatase PP1 and Inhibitor-3. SDS22:PP1:Inhibitor-3 is a substrate for the ATPase p97/VCP, which liberates PP1 for binding to canonical regulatory subunits. The exact role of SDS22 in PP1-holoenzyme

Protein phosphatase 1 dephosphorylates profilin-1 at Ser-137. [PDF]
Profilin-1 (PFN1) plays an important role in the control of actin dynamics, and could represent an important therapeutic target in several diseases. We previously identified PFN1 as a huntingtin aggregation inhibitor, and others have implicated it as a ...
