Cell Cycle/Checkpoint Cell Cycle/CheckpointPLK
Polo-like kinase (PLK) is a highly conserved serine/threonine protein kinase with a highly homologous serine/threonine kinase domain at its N-terminus, which regulates PLK activity and subcellular dynamics at the C-terminus and targeted polo-box domain (PBD). There are many PLK family members, and there are four subtypes in the human body, namely PLK1, PLK2, PLK3, and PLK4, which play important roles in the regulation of various phases of the cell cycle.
