NCIt definition : Human PLK3 wild-type allele is located in the vicinity of 1p34.1 and is approximately
6 kb in length. This allele, which encodes serine/threonine-protein kinase PLK3 protein,
plays a role in the regulation of M phase functions during the cell cycle. The PLK3
gene is down-regulated in certain types of cancer (head and neck squamous cell carcinomas,
lung carcinomas) and overexpressed in other types of cancer (breast carcinomas and
highly-proliferating malignant epithelial ovarian tumors).;
NCIt note : The PLK3 gene is putatively involved in regulation of cell cycle progression and tumorigenesis.
It may also play a role in controlling cellular adhesion. In breast carcinomas, PLK3
gene expression is significantly correlated with patient survival time.;
