Overview of Gene Research
Ppm1k, also named as PP2Cm or branched-chain α-ketoacid dehydrogenase complex phosphatase, is a member of the metal-dependent phosphatase family. It is predominantly located in the mitochondrial matrix and plays a crucial role in the metabolism of branched-chain amino acids (BCAAs) [3,4]. It is also involved in various cellular functions and development across different tissues [4]. Genetic models, like knockout mouse models, are valuable for studying its functions [1].
In Ppm1k-deficient female mice, BCAA levels increased, and they exhibited PCOS-like traits such as hyperandrogenemia and abnormal follicle development [1]. This shows that Ppm1k deficiency-impaired BCAA catabolism can cause the occurrence and development of PCOS [1]. Also, knockdown of PPM1K in neurons led to defective BCAA catabolism, which induced neuronal ferroptosis after cerebral ischemia-reperfusion injury [2].
In conclusion, Ppm1k is essential for the regulation of BCAA metabolism. Model-based research, especially using Ppm1k KO mouse models, has revealed its role in diseases like PCOS and cerebral ischemia-reperfusion injury, highlighting its importance in understanding the mechanisms of these diseases and potentially guiding therapeutic strategies [1,2].
