obsolete normal protein serine phosphorylation at RxxS site during vegetative growth true 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. 2015-10-28T14:44:44Z FYPO:0004422 normal protein serine phosphorylation at phospho-Akt site during vegetative growth normal peptidyl-serine phosphorylation at RxxS site during vegetative growth normal protein serine phosphorylation at PAS site during vegetative growth FYPO:0005007 midori normal protein serine phosphorylation at RxxS site during mitotic cell cycle normal protein serine phosphorylation at arginine-X-X-serine site during vegetative growth normal protein serine phosphorylation at Arg-X-X-Ser site during vegetative growth OBSOLETE. A cellular process phenotype observed in the vegetative growth phase of the life cycle in which the of serine residues three positions C-terminal to arginine residues (i.e. in Arg-X-X-Ser, or RxxS, sequences) is normal (i.e. indistinguishable from wild type).
