The Role of Phosducin-like Protein as a Co-chaperone with the Cytosolic Chaperonin Complex in Assembly of the G Protein βγ Subunit Dimer
<p>Phosducin-like protein (PhLP) has been shown to interact with the cytosolic chaperonin containing TCP-1 (CCT), and the βγ subunit dimer of heterotrimeric G proteins (Gβγ). Here we provide details obtained from cryo-electron microscopic and biochemical studies on the structure of the complex …

The Mechanism of Assembly of the G-Protein Beta Gamma Subunit Dimer by CK2 Phosphorylated Phosducin-Like Protein and the Chaperonin Containing TCP-1
Phosducin-like protein (PhLP) binds G-protein beta gamma subunits and is thought to assist in assembly of the G-protein beta gamma dimer. Phosphorylation of PhLP at serine residues 18-20 by the casein kinase 2 (CK2) appears to play an essential role in this process. PhLP has also been shown to …

The Role of Phosducin-like Protein and the Cytosolic Chaperonin CCT in G beta gamma dimer Assembly
<p>Phosducin-like protein (PhLP), a G protein beta gamma subunit dimer binder and G protein signaling regulator, was suggested to regulate the activity of cytosolic chaperonin CCT by their high affinity interaction. In the present study, the three-dimensional structure of PhLP:CCT complex has been …

Development of Methods for the Study of Phosphoproteins
Characterization of phosphoproteins-including detection, identification of phosphoproteins and identification of phosphorylation sites-is mostly done with radiolabeling and proteomic techniques. Three main topics related to phosphoprotein characterization are included in this dissertation. First, …

Role of Chaperonin CCT in G-protein Biosynthesis
… and function to assist the folding of other proteins. All chaperonins consist of two stacked rings, which come together to form a central cavity where folding can take place. The eukaryotic cytosolic chaperonin containing TCP1 (CCT) is a member of the group II chaperonins, which are defined …
