In this review, belongs to the calcium/calmodulin-dependent kinase family, we present and discuss the current landscape of studies and is involved in multiple mechanisms implicated in tumor investigating the role of PKD1 in the proliferation of both progression such as cell motility, invasion, proliferation, pro- cancerous and normal cells.
