WebAutophosphorylation is a type of post-translational modification of proteins.It is generally defined as the phosphorylation of the kinase by itself. In eukaryotes, this process occurs by the addition of a phosphate group to serine, threonine or tyrosine residues within protein kinases, normally to regulate the catalytic activity. Autophosphorylation may occur when … Web22 Oct 2024 · PP2A-B55 also plays a pivotal role in mitotic entry and exit. The G2-M transition is induced by the activation of cyclin B/Cdk1. This activation is modulated by a double feedback loop. One of ...
