Overview of Gene Research
DNAJC19, a member of the DNAJ heat shock protein (Hsp40) family, is located within the inner mitochondrial membrane. It plays a crucial role in regulating the function and localization of mitochondrial Hsp70 (MtHsp70) and is involved in mitochondrial protein import machinery [3,5]. It also forms a complex with prohibitins to regulate cardiolipin remodeling, which is essential for mitochondrial morphogenesis [4].

Mutations in DNAJC19 cause Dilated Cardiomyopathy with Ataxia Syndrome (DCMA). In human iPSC-derived cardiomyocytes with mutant DNAJC19 lacking the conserved DnaJ interaction domain, there are mitochondrial fragmentation, abnormal cristae formation, increased mitochondrial respiration, and altered substrate utilization [2]. In NSCLC, DNAJC19 expression is higher in tumors than adjacent non-cancerous tissues. shRNA-mediated knockdown of DNAJC19 in A549 lung cancer cells inhibits cell growth, viability, migration, and invasion, and represses tumor xenograft growth and lung metastasis by regulating the PI3K/AKT signaling pathway [1].

In conclusion, DNAJC19 is essential for mitochondrial function, including mitochondrial morphogenesis and cardiolipin remodeling. Its dysregulation is associated with DCMA and NSCLC. Studies using gene-edited cell lines and knockdown models in cancer cells have revealed its role in these disease conditions, providing potential therapeutic targets.
