Target data

Function

Inhibitor of protein-phosphatase 1. This protein may be important in hormonal control of glycogen metabolism. Hormones that elevate intracellular cAMP increase I-1 activity in many tissues. I-1 activation may impose cAMP control over proteins that are not directly phosphorylated by PKA. Following a rise in intracellular calcium, I-1 is inactivated by calcineurin (or PP2B). Does not inhibit type-2 phosphatases.

Alternative names

IPP1, PPP1R1A, Protein phosphatase 1 regulatory subunit 1A, Protein phosphatase inhibitor 1, I-1, IPP-1

Activity summary

The protein phosphatase 1 regulatory inhibitor subunit 1A also known as PPP1R1A or inhibitor-1 (I-1) plays a significant role in cellular regulation as a phosphatase inhibitor. Mechanically it regulates the activity of protein phosphatase 1 (PP1) an essential enzyme in various cellular processes. Its molecular weight is approximately 19 kDa. PPP1R1A is expressed in many tissues showing notable levels in cardiac and skeletal muscle where it helps modulate responses to various stimuli.

Biological function summary

PPP1R1A modulates signaling pathways by influencing the dephosphorylation of substrates which is a critical step in signal transduction. It is not typically part of a complex but interacts closely with protein phosphatase 1. This interaction allows for the effective regulation of phosphorylation states within cells impacting cell cycle control muscle contraction glycogen metabolism and more. Its regulatory capabilities are important for maintaining cellular homeostasis.

Pathways

The regulatory activities of PPP1R1A significantly impact the cAMP signaling pathway and the regulation of glycogen metabolism. Within the cAMP pathway PPP1R1A regulates the activity of PP1 influencing processes like muscle contraction and gene expression. It interacts with proteins such as PKA which phosphorylates PPP1R1A activating its inhibitory function. This regulation affects downstream cellular activities by modulating phosphorylation levels of key substrates within these pathways.

Associated diseases and disorders

Alterations in PPP1R1A expression or function have implications in cardiac diseases and diabetes. Increased or decreased activity of PPP1R1A can disrupt normal heart function due to its regulatory role in cardiac muscle contraction. Altered regulation within the cAMP and glycogen metabolism pathways can contribute to metabolic disorders like diabetes. Interactions with proteins such as PP1 and PKA are critical for these conditions highlighting PPP1R1A's role in disease progression and potential therapeutic targeting.

    ICC/IF image of ab40877 stained PC12 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab40877, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
