Phenylketonuria (PKU) treatment requires a low-phenylalanine (Phe) diet limiting natural protein intake, using medical low-protein foods and Phe-free amino acids (AA) supplements along with micronutriments' supplies. Current recommendations suggest maintaining this diet for life to prevent neuro-psychological effects of high Phe concentrations. The long-term consequences of such a diet are poorly understood, particularly on bone health.

Background And Objective: Adult patients with early-treated phenylketonuria (AwET-PKU) may present some subtle neurocognitive deficits. The aim of the study was to investigate 1) neurocognitive functions in a large group of AwET-PKU 2) the influence of plasma phenylalanine (Phe).

Methods: Participants: 187 AwET-PKU (classic PKU [cPKU] 81%, mild PKU [mPKU] 14%, and mild persistent hyperphenylalaninemia [MPH] 5%).

Notch activation complex kinase (NACK) is a component of the Notch transcriptional machinery critical for the Notch-mediated tumorigenesis. However, the mechanism through which NACK regulates Notch-mediated transcription is not well understood. Here, we demonstrate that NACK binds and hydrolyzes ATP and that only ATP-bound NACK can bind to the Notch ternary complex (NTC).
