obsolete abolished protein serine phosphorylation at RxxS site during cellular response to hydroxyurea true abolished protein serine phosphorylation at RxxS site during cellular response to hydroxyurea during vegetative growth abolished protein serine phosphorylation at RxxS site during cellular response to hydroxyurea during mitotic cell cycle protein serine phosphorylation abolished at RxxS site during cellular response to hydroxyurea midori abolished protein serine phosphorylation at Arg-X-X-Ser site during cellular response to hydroxyurea This term was made obsolete to implement a decision that protein modification terms should only include residue-specific information in cases where it is especially biologically significant, such as in histones or the RNA polymerase II CTD. In all other cases, phenotypic effects on specific modified residues should be captured in annotation extensions. FYPO:0004550 abolished protein serine phosphorylation at phospho-Akt site during cellular response to hydroxyurea abolished protein serine phosphorylation at PAS site during cellular response to hydroxyurea abolished protein serine phosphorylation at RxxS site during cellular response to HU abolished protein serine phosphorylation at arginine-X-X-serine site during cellular response to hydroxyurea OBSOLETE. A cellular process phenotype observed in the vegetative growth phase of the life cycle in which the phosphorylation of serine residues three positions C-terminal to arginine residues (i.e. in Arg-X-X-Ser, or RxxS, sequences) does not occur during a cellular response to hydroxyurea.
