Interaction of oncoprotein transcription factor MYC with chromatin-associated protein host cell factor–1 controls expression of genes important for ribosome biogenesis and mitochondrial vigor, loss of which promotes tumor regression.

We reveal TAPBPR is a peptide exchange catalyst which restricts the peptide repertoire presented by MHC I on cells, a finding which has important implications for all aspects of immune recognition.

Myc-dependent induction of amino acid transporter expression in response to T cell receptor activation is essential to enable T cell proteome remodelling upon immune activation.
The endoplasmic reticulum (ER) folding sensor UGGT1 essentially cooperates with the peptide editor TAPBPR to provide quality control of MHC I molecules in the antigen presentation pathway.
A new potent and selective CDK9 inhibitor induces the expression of the proto-oncogene MYC via a mechanism that depends on the bromodomain protein BRD4.

The number of different peptides presented by major histocompatibility complex class I molecules to the immune system's T lymphocytes is inversely correlated with cell surface expression and is strongly associated with the response to infectious disease.

The recently discovered peptide editor TAPBPR binds to UDP-glucose:glycoprotein glucosyltransferase 1 to provide quality control in the antigen presentation pathway by facilitating the reglucosylation of the glycan on MHC class I molecules.

MYC and Twist1 drive metastasis by a novel non-cell-autonomous transcriptional mechanism of eliciting a cytokinome that mediates the crosstalk between cancer cells and macrophages, and its therapeutic blockade inhibits metastasis.

Epstein-Barr virus controls B-cell growth and survival through large-scale reorganization of the enhancers of the MYC and BCL2L11 genes, and may promote MYC translocations as a result.
