Glucose and related sugars repress the transcription of genes encoding enzymes required
for the utilization of alternative carbon sources; some of these genes are also repressed by …

The tetratricopeptide repeat (TPR) motif is a protein‐protein interaction module found in
multiple copies in a number of functionally different proteins that facilitates specific …

Tetratrico peptide repeat (TPR) proteins have several interesting properties, including their
folding characteristics, modular architecture and range of binding specificities. In the past …

Intraflagellar transport (IFT) is a rapid movement of multi-subunit protein particles along
flagellar microtubules and is required for assembly and maintenance of eukaryotic flagella …

The chaperone function of the mammalian 70-kDa heat shock proteins Hsc70 and Hsp70 is
modulated by physical interactions with four previously identified chaperone cofactors …

O-Linked N-acetylglucosamine (O-GlcNAc) glycosylation is a dynamic modification of
eukaryotic nuclear and cytosolic proteins analogous to protein phosphorylation. We have …

Oscillations in the activity of cyclin-dependent kinases (CDKs) promote progression through
the eukaryotic cell cycle. This review examines how proteolysis regulates CDK activity—by …

The tetratricopeptide repeat (TPR) is a degenerate 34 amino acid sequence identified in a
wide variety of proteins, present in tandem arrays of 3–16 motifs, which form scaffolds to …

Anaphase initiation has been postulated to be controlled through the ubiquitin-dependent
proteolysis of an unknown inhibitor. This process involves the anaphase promoting complex …

Tetrapyrroles such as chlorophylls and bacteriochlorophylls play a fundamental role in the
energy absorption and transduction activities of photosynthetic organisms. Because of these …
