It is possible to remove serine by targeting mutagenesis and then observe how this modification changes the function of the protein in the cell. Serine is often a target for phosphorylation.
Serine is one fundamental amino acid, i.e., a building block of biomolecules called proteins.
Serine is often a target for posttranslational modifications, especially protein phosphorylation.
In a given cell, serine phosphorylation may activate or deactivate specific signaling pathways.
In this case, it is possible to identify other serine proteases by sequence homo-logy using the BLAST bioinformatic tool.
