1. Hoxb1b is likely to directly regulate ppp1r14al expression in rhombomere 4. Furthermore, ppp1r14al is essential for establishment of the earliest hindbrain signaling-center in rhombomere 4 by regulating expression of fgf3 (Montrer FGF3 Protéines).

1. CPI-17 drives Ras activity and tumorigenesis in melanomas in a two-fold way; inactivation of the tumor suppressor merlin (Montrer NF2 Protéines) and activation of the growth promoting ERM (Montrer ETV5 Protéines) family.

2. The authors call the mutual sequestration mechanism through which pCPI-17 and myosin light-chain phosphatase interact inhibition by unfair competition: myosin light-chain phosphatase protects pCPI-17 from other phosphatases, while pCPI-17 blocks other substrates from the active site of myosin light-chain phosphatase.

3. Study finds that CPI-17 (PPP1R14A protein phosphatase 1 regulatory inhibitor subunit 14A, 17 kDa) is not expressed in the healthy peripheral nervous system or in nontumour pathologies of the peripheral nervous system. CPI-17 up-regulation, however, is observed in over 90% of schwannomas, but not in neurofibroma and only rarely in malignant peripheral nerve sheath tumour.

4. CPI-17 has a role in restoring skin homoeostasis in cutaneous field of cancerization lesions

5. analysis of the interaction between plakoglobin (Montrer JUP Protéines) and CPI-17, which is affected by the phosphorylation status of CPI-17 in human lung microvascular endothelial cells

6. The N-terminal 21-residue tail domain of CPI-17 is necessary for nuclear localization. Phospho-mimetic Asp (Montrer ASIP Protéines)-substitution of CPI-17 at Ser12 attenuates the nuclear import.

7. The study characterized the CPI-17 promoter and identified binding sites for GATA-6 (Montrer GATA6 Protéines) and nuclear factor kappa B (NF-kappaB (Montrer NFKB1 Protéines)).

8. a novel signaling cascade that links RhoA (Montrer RHOA Protéines)-mediated calcium sensitivity to MEF2 (Montrer MEF2A Protéines)-dependent myocardin expression in VSMCs through a mechanism involving p38 MAPK (Montrer MAPK14 Protéines), PP1alpha (Montrer PPP1CA Protéines), and CPI-17.

9. RACK1 (Montrer GNB2L1 Protéines) may play a role in PKC (Montrer PRRT2 Protéines)/CPI-17 signaling pathway.

10. cAMP/PKA regulates the endothelial barrier via inhibition of the contractile machinery, mainly by the activation of MLCP via inhibition of CPI-17 and RhoA (Montrer RHOA Protéines)/Rock.

1. Enhanced vasorelaxation in early endotoxemia is mediated by redox signaling through PKG-1alpha but in later endotoxemia by myosin phosphatase isoform shifts enhancing sensitivity to NO/cGMP as well as smooth muscle atrophy.

2. The study characterized the CPI-17 promoter and identified binding sites for GATA-6 (Montrer GATA6 Protéines) and nuclear factor kappa B (NF-kappaB (Montrer NFKB1 Protéines)).

3. a novel signaling cascade that links RhoA (Montrer RHOA Protéines)-mediated calcium sensitivity to MEF2 (Montrer MEF2C Protéines)-dependent myocardin expression in VSMCs through a mechanism involving p38 MAPK (Montrer MAPK14 Protéines), PP1alpha (Montrer PPP1CA Protéines), and CPI-17.

4. Data suggest that CPI-17 and both conventional and novel PKC isozymes contribute to the phasic and tonic contractile components of BALB/c colonic circular smooth muscle.

5. Organ-specific mechanisms involving MYPT1 (Montrer PPP1R12A Protéines), M-RIP, and CPI-17 are critical to regulating basal LC20 (Montrer MYL9 Protéines) phosphorylation in gastrointestinal smooth muscles.

6. calcium-independent phospholipase A2beta has a role in high glucose-induced activation of RhoA (Montrer RHOA Protéines), Rho kinase (Montrer ROCK2 Protéines), and CPI-17 in cultured vascular smooth muscle cells and vascular smooth muscle hypercontractility in diabetic animals

7. distribution of mouse and rat PPP1R14A was more specific and different from that of humans

8. concluded that actions downstream of cGMP/PKG (Montrer PRKG1 Protéines) can reverse PKC-mediated phosphorylation of CPI-17 and Ca(2 (Montrer CA2 Protéines)+) sensitization in smooth muscle

9. findings suggest that CPI-17 was downregulated during intestinal inflammation and that TNF-alpha (Montrer TNF Protéines) plays a central role in this process. Downregulation of CPI-17 may play a role in motility impairments in inflammation.

10. CPI-17 expression is reversibly controlled in response to the phenotype transition of smooth muscle cells that restricts the signal to differentiated smooth muscle cells and particular cell types.

1. This study examined the protein expression and spatial-temporal distribution of PKCalpha (Montrer PKCa Protéines) and CPI-17 in intact smooth muscle tissues.
