Overview of Gene Research
Wdr24 is an essential component of the GATOR2 complex. The GATOR2 complex is crucial in the nutrient-sensing machinery, specifically in linking amino acid signals to mTORC1, a central regulator of metabolism and cell growth [2,3,4,5,6]. It also has a role in the glucose-sensing capability of mTORC1 [3].
In gene knockout studies, Wdr24 ablation in mice leads to severe growth defects and embryonic lethality at E10.5, preventing mTORC1 activation, which reveals its essentiality during embryonic development [4]. Phosphomimetic Wdr24S155D knock-in mice exhibit early embryonic lethality and reduced mTORC1 activity, while phospho-deficient Wdr24S155A knock-in mice are more resistant to fasting and display elevated mTORC1 activity, indicating the role of AMPK-mediated phosphorylation of Wdr24 in modulating glucose-induced mTORC1 activation [3]. In Drosophila, Wdr24 is a critical effector of the GATOR2 complex, promoting TORC1 activation and cellular growth, and also has a TORC1-independent role in regulating lysosome dynamics and autophagic flux [7].
In conclusion, Wdr24 is key for mTORC1 activation in response to amino acids and glucose, playing a vital role in embryonic development and cellular metabolism. Mouse models, including gene knockouts and knock-ins, have been instrumental in revealing its functions, with implications for understanding diseases related to abnormal mTORC1 signaling, such as cancer [1,3,4,6].
