As a scaffold protein for the assembly and maintenance of centriolar satellites, pericentriolar material 1 (PCM1) is essential for proper ciliogenesis and ciliary functions, and Pcm1 knockout mice display ciliopathy-associated phenotypes such as dwarfism, hydronephrosis, and male infertility (Odabasi et al., 2020; Hall et al., 2023). Here, PCM1 is linked to hydronephrosis.
