Rho-associated kinase (Rho-kinase), the putative target of the small GTP-binding protein Rho, phosphorylated neurofilament protein (NF-L) in vitro with approximately 1 mole phosphate per mole NF-L. Phosphorylated NF-L no longer formed the 10 nm filaments, and NF-L filaments were phosphorylated with a result of nearly complete disassembly. NF-L phosphorylated by Rho-kinase was digested with trypsin, and digested fragments were assigned by MALDI/TOF. Unique phosphorylation sites were found at Ser-26 and Ser-57 in the head domain of NF-L. These results indicate that domain- and site-specific phosphorylation by Rho-kinase may regulate the assembly-disassembly of NF-L filaments.
