Gene Gene information from NCBI Gene database.
Entrez ID 5347
Gene name Polo like kinase 1
Gene symbol PLK1
Synonyms (NCBI Gene)
PLKSTPK13
Chromosome 16
Chromosome location 16p12.2
Summary The Ser/Thr protein kinase encoded by this gene belongs to the CDC5/Polo subfamily. It is highly expressed during mitosis and elevated levels are found in many different types of cancer. Depletion of this protein in cancer cells dramatically inhibited cel
