Human Plakophilin 4 (PKP4) interaction partners

1. p0071 is required for directional vesicle movement and secretion of different KIF3-transported carriers, thereby regulating the transport of intracellular membrane vesicles along microtubules.

2. Data show that patients with both abnormal expression of p0071 and E-cadherin had a statistically significant shorter survival than the patients without both abnormal expression.

3. p0071 has a key role in regulating recycling through the Rab11a-dependent perinuclear recycling compartment.

4. This review article focuses on the functions of the p0071 protein and its closest relatives in regulating cell adhesion and cytoskeletal organization, which are critically involved in the control of cell polarity. [review]

5. Findings suggest that aspects of folliculin tumour suppressor function are linked to interaction with p0071 and the regulation of RhoA signalling.

6. These data support a model in which dysregulation of the FLCN-p0071 interaction leads to alterations in cell adhesion, cell polarity, and RhoA signaling.

7. The structural and functional roles of p0071 are suggested by its preferential occurrence in distinct tubule segments, and its potential use as a cytodiagnostic cell type marker in renal pathology is discussed.

8. ERBIN interacts in vivo with p0071 and that it may be involved in the organization of adherens junctions and the desmosomes of epithelia

9. In addition to plakoglobin, p0071 is the second armadillo protein present in both types of adhesive junctions and may play a role in regulating crosstalk between adherens junctions and desmosomes.

10. p0071 bound to the first 160 amino-terminal residues of desmoplakin and also interacted directly with plakoglobin, suggesting that p0071 may regulate desmosome assembly by controlling plakoglobin availability

11. These findings support an essential role for p0071 in spatially regulating restricted Rho signalling during cytokinesis.

12. In this review p0071 catenin, a close relative of p120 catenin, associates and regulates RhoA-GTPase at the cleavage furrow during cytokinesis.

13. Protein p0071 has been localized as a plaque protein in adhaerens junctions of diverse epithelia and certain vascular endothelia.

14. Data indicate that p0071 and Ect2 are transported via distinct motors and identify a novel pathway implicating KIF3 in the regulation of actin organization during cytokinesis.

15. Using shotgun mass spectrometry, we found this protein differentially expressed in the dorsolateral prefrontal cortex from patients with schizophrenia.

Mouse (Murine) Plakophilin 4 (PKP4) interaction partners

1. results identify p0071 as an important and novel FMRP target and strongly suggest that impaired actin cytoskeletal functions mediated by an excess of p0071 are key aspects underlying the fragile X syndrome

2. These data support a model in which dysregulation of the FLCN-p0071 interaction leads to alterations in cell adhesion, cell polarity, and RhoA signaling.
