The second identified substrate of PAS kinase discussed is Pbp1. The human homolog of Pbp1 is ataxin-2, mutations in which are a known risk factor for amyotrophic lateral sclerosis (ALS). As diet and sex have been shown to be important factors regarding PAS kinase function, they also are strong contributing factors to ALS and are extensively reviewed herein. Pbp1 is known to be sequestered by PAS kinase under glucose depravation, and it can sequester additional proteins along with it to regulate different cellular pathways. To shed light on the pathways affected by Pbp1, we performed a yeast two-hybrid assay and …

Nutrient sensing kinases lie at the heart of cellular health and homeostasis, allowing cells to quickly adapt to changing environments. Target of Rapamycin (TOR) and PAS kinase (PASK, or PASKIN) are two such nutrient kinases, conserved from yeast to man. In yeast, these kinases each have paralogs. The two TOR paralogs in yeast mimic the mammalian TORC1 and TORC2 complexes, except both Tor1 and Tor2 may contribute to TORC1 or TORC2 function. The two PAS kinase paralogs are paired with the TOR paralogs, meaning that both Psk1 and Psk2 regulate TORC1, while Psk2 suppresses a temperature-sensitive allele of Tor2. Herein …
