obsolete normal protein tyrosine phosphorylation during vegetative growth true FYPO:0000776 FYPO:0004661 OBSOLETE. A cellular process phenotype observed in the vegetative growth phase of the life cycle in which the phosphorylation of tyrosine residues of one or more specific proteins is normal (i.e. indistinguishable from wild type). 2015-05-27T16:42:15Z 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. normal protein tyrosine phosphorylation during mitotic cell cycle midori
