PTMprosessit
PTMprosessit, or Post-Translational Modifications, are chemical alterations that occur after a protein has been translated from its corresponding messenger RNA (mRNA). These modifications play a crucial role in regulating protein function, stability, and localization within the cell. PTMs can occur on various amino acid residues, including serine, threonine, tyrosine, and cysteine, and can involve the addition, removal, or alteration of chemical groups.
One of the most common PTMs is phosphorylation, where a phosphate group is added to a hydroxyl
PTMs can also involve the addition of small ubiquitin-like modifiers (SUMOs), which regulate protein localization, stability,
PTMs are essential for various cellular processes, including cell cycle regulation, gene expression, and signal transduction.
