Mice Lacking p27Kip1 Display Increased Body Size, Multiple Organ Hyperplasia, Retinal Dysplasia, and Pituitary Tumors
SUMMARY Mice lacking p27(Kip1) have been created by gene targeting in embryonic stem cells. These mice are larger than the control animals, with thymus, pituitary, and adrenal glands and gonadalExpand

Targeted disruption of Skp2 results in accumulation of cyclin E and p27Kip1, polyploidy and centrosome overduplication
The ubiquitin–proteasome pathway plays an important role in control of the abundance of cell cycle regulators. Mice lacking Skp2, an F‐box protein and substrate recognition component of anExpand

Inherent calcineurin inhibitor FKBP38 targets Bcl-2 to mitochondria and inhibits apoptosis
The mitochondrial localization of the membrane proteins Bcl-2 and Bcl-xL is essential for their anti-apoptotic function. Here we show that mitochondrial FK506-binding protein 38 (FKBP38), unlikeExpand

An F‐box protein, FWD1, mediates ubiquitin‐dependent proteolysis of β‐catenin
β‐catenin plays an essential role in the Wingless/Wnt signaling cascade and is a component of the cadherin cell adhesion complex. Deregulation of β‐catenin accumulation as a result of mutations inExpand

Protrudin Induces Neurite Formation by Directional Membrane Trafficking
Guanosine triphosphatases of the Rab family are key regulators of membrane trafficking, with Rab11 playing a specific role in membrane recycling. We identified a mammalian protein, protrudin, thatExpand

Promotion of Neurite Extension by Protrudin Requires Its Interaction with Vesicle-associated Membrane Protein-associated Protein
Protrudin is a protein that contains a Rab11-binding domain and a FYVE (lipid-binding) domain and that functions to promote neurite formation through interaction with the GDP-bound form of Rab11.Expand

Down-regulation of p27 Kip1 by Two Mechanisms, Ubiquitin-mediated Degradation and Proteolytic Processing*
The intracellular level of p27 Kip1 , a cyclin-dependent kinase (CDK) inhibitory protein, is rapidly reduced at the G1/S transition phase when the cell cycle pause ceases. In this study, weExpand

Interaction of presenilins with FKBP38 promotes apoptosis by reducing mitochondrial Bcl-2.
Presenilins 1 and 2 (PS1/2), causative molecules for familial Alzheimer's disease (FAD), are multipass transmembrane proteins localized predominantly in the endoplasmic reticulum (ER) and GolgiExpand

Selective escape of proteins from the mitochondria during mitophagy.
Mitophagy refers to the degradation of mitochondria by the autophagy system that is regulated by Parkin and PINK1, mutations in the genes for which have been linked to Parkinson's disease. Here weExpand

Protrudin Regulates Endoplasmic Reticulum Morphology and Function Associated with the Pathogenesis of Hereditary Spastic Paraplegia*
Background: Certain hereditary spastic paraplegia (HSP)-related proteins possess hairpin domains and regulate the morphology of the endoplasmic reticulum (ER) network. Results: Protrudin possesses aExpand
