PPP1R11 also known as Protein Phosphatase 1 Regulatory Inhibitor Subunit 11 is a protein that acts as an inhibitor of protein phosphatase 1 (PP1) activity. It weighs approximately 14 kDa and is expressed in various tissues with higher levels in the testis and less in other tissues. Its primary role involves binding to PP1 a critical enzyme in the regulation of phosphorylation states within cells and modulating its activity.

Biological function summary

The protein regulates the phosphorylation process which is vital for cellular functions. PPP1R11 does not work in isolation; it forms part of a complex with PP1 influencing the enzyme's ability to dephosphorylate target substrates. This function is essential in controlling cell division protein synthesis and muscle contractility through its inhibition effect on PP1.

Pathways

PPP1R11 contributes significantly to cellular signaling pathways. It plays a role in the cell cycle regulation pathway and also the glycogen metabolism pathway. Within these pathways it interacts with PP1 and other regulatory proteins to maintain proper cellular functions and energy management. Alterations in these interactions can lead to dysregulation exhibiting the target's importance in cell physiology.

The alterations in the function or expression of PPP1R11 link to certain cancers and metabolic conditions. Its connection with PP1 shows a relationship with cancer through irregular cell cycle control. Furthermore its role in glycogen metabolism can relate to disorders like type 2 diabetes highlighting the interaction with insulin-regulatory proteins. Understanding PPP1R11’s function can help develop potential interventions for these conditions.
