Sperm-specific fertility factors SMZ-1/2 promote FB-MO biogenesis and MSP filament assembly in C. elegans

Abstract In nematode sperm, motility is powered by polymerization of major sperm protein (MSP) into filaments assembled from a specialized organelle (FB–MO), but how filament formation begins is unclear. We identify two sperm-specific PDZ proteins, SMZ-1 and SMZ-2 (SMZ-1/2), that...
