Myopathy associated LDB3 mutation causes Z-disc disassembly and protein aggregation through PKCα and TSC2-mTOR downregulation

Pathak et al. identify LDB3, a striated muscle PDZ-LIM protein, as a signaling adaptor in a major mechanosensor assembly through interactions with filamin C, HSPA8, and PKCα. When LDB3 is mutated, PKCα and TSC2-mTOR mediated homeostasis is impaired, leading to protein aggregation myopathy.
