HIPK1
Homeodomain-interacting protein kinase 1 is an enzyme that in humans is encoded by the "HIPK1" gene. Function. The protein encoded by this gene belongs to the Ser/Thr family of protein kinases and HIPK subfamily. It phosphorylates homeodomain transcription factors and may also function as a co-repressor for homeodomain transcription factors. Alternative splicing results in four transcript variants encoding four distinct isoforms. Interactions. HIPK1 has been shown to interact with P53.
