In all other cases, phenotypic effects on specific modified residues should be captured in annotation extensions. increased protein serine phosphorylation at Arg-X-X-Ser site during nitrogen starvation 2015-10-28T14:53:19Z increased protein serine phosphorylation at RxxS site during nitrogen depletion increased protein serine phosphorylation at phospho-Akt site during nitrogen starvation OBSOLETE. A cellular process phenotype in which the phosphorylation of serine residues three positions C-terminal to arginine residues (i.e. in Arg-X-X-Ser, or RxxS, sequences) occurs to a greater extent than normal when the cell is subject to nitrogen starvation.
