obsolete normal protein serine phosphorylation true midori FYPO:0004422 OBSOLETE. A cellular process phenotype in which the phosphorylation of serine residues of one or more specific proteins is normal (i.e. indistinguishable from wild type). FYPO:0005006 2015-10-28T14:44:03Z normal peptidyl-serine phosphorylation 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.
