Patients at FP hemodialysis facilities have 7 percent greater odds of death annually than patients with similar risk profiles at NFP facilities. Approximately 3,800 excess deaths might be averted annually if U.S. FP hemodialysis operators matched NFP mortality rates.Polo-like kinase 4 (Plk4) is a key regulator of centriole biogenesis. Studies have shown that Plk4 undergoes dynamic relocalization from a ring-like pattern around a centriole to a dot-like morphology at the procentriole assembly site and this event is central for inducing centriole biogenesis. However, the detailed mechanisms underlying Plk4's capacity to drive its symmetry-breaking ring-to-dot relocalization remain largely unknown. Here, we showed that Plk4 self-initiates this process in an autophosphorylation-dependent manner and that STIL, its downstream target, is not required for this event. Time-dependent analyses with mEOS-fused photoconvertible Plk4 revealed that a portion of ring-state Plk4 acquires a capacity, presumably through autophosphorylation, to linger around a centriole, ultimately generating a dot-state morphology. Interestingly, Plk4 WT, but not its catalytically inactive mutant, showed the ability to form a nanoscale spherical assembly in the cytosol of human cells or heterologous E. coli, demonstrating its autophosphorylation-dependent self-organizing capacity. At the biochemical level, Plk4 - unlike its N-terminal βTrCP degron motif - robustly autophosphorylated the PC3 SSTT motif within its C-terminal cryptic polo-box, an event critical for inducing its physical clustering. Additional in vivo experiments showed that although STIL was not required for Plk4's initial ring-to-dot conversion, coexpressed STIL greatly enhanced Plk4's ability to generate a spherical condensate and recruit Sas6, a major component of the centriolar cartwheel structure. We propose that Plk4's autophosphorylation-induced clustering is
