1. Protein Quality Control at the Inner Nuclear Membrane – The Asi complex in Saccharomyces cerevisiae
Sammanfattning : The nuclear envelope is a barrier comprised of outer and inner membranes that separate the cytoplasm from the nucleoplasm. The outer (ONM) and inner (INM) membranes have different physical characteristics and protein compositions. LÄS MER
2. Mechanisms of modulation of PDGFRβ signaling
Sammanfattning : Platelet-derived growth factors (PDGF) constitute a family of five functional dimers that bind to two structurally related tyrosine kinase receptors i.e. PDGF receptor α and β (PDGFRα and PDGFRβ, respectively), controlling cell growth, proliferation, and migration in cells of mesenchymal origin.

3. Regulation of TGF-β Signaling by Post-Translational Modifications
Sammanfattning : Transforming growth factor-β (TGF-β) signaling is initiated when the ligand binds to type II and type I serine/threonine kinase receptors at the cell surface. Activated TGF-β type I receptors phosphorylate R-Smads which relocate, together with co-Smads, to the cell nucleus and regulate transcription. LÄS MER
4. Interplay between the Myc oncoprotein, cyclin-dependent kinases and E3 ubiquitin ligases
Sammanfattning : Mammalian cells grow, divide, and die in a precise and orderly fashion. For cells to grow and maintain their integrity they need to communicate at both intracellular and extracellular level. LÄS MER
5. Modulation of nuclear receptor signaling by RBR ubiquitin ligases
Sammanfattning : Nuclear receptors (NRs) constitute a superfamily of transcription factors and play important roles in physiology. Transcriptional regulation by NRs can be modulated through interactions with various coregulators that activate or repress transcription through mediating receptor and chromatin modifications as well as communicating with the general transcription factor machinery.
