A robust workflow for the identification of proline hydroxylation sites in proteins was established, using hydrophilic interaction chromatography enrichment and LC-MS/MS together with refining and filtering parameters during data analysis.
Proline hydroxylation of RepoMan (CDCA2) at P604 by PHD1 is shown to be important for mitotic progression and regulating interaction with PP2A regulatory subunit B56 gamma.
The viral type 2 internal ribosome entry site uses a unique mechanism to hijack the host ribosomal machinery by interacting with initiator tRNA and 40S head.
