Summaries for PLK4 Gene

Entrez Gene Summary for PLK4 Gene

  • This gene encodes a member of the polo family of serine/threonine protein kinases. The protein localizes to centrioles, complex microtubule-based structures found in centrosomes, and regulates centriole duplication during the cell cycle. Three alternatively spliced transcript variants that encode different protein isoforms have been found for this gene. [provided by RefSeq, Jun 2010]

GeneCards Summary for PLK4 Gene

PLK4 (Polo Like Kinase 4) is a Protein Coding gene. Diseases associated with PLK4 include microcephaly and chorioretinopathy, autosomal recessive, 2 and seckel syndrome. Among its related pathways are FoxO signaling pathway and DNA Damage. GO annotations related to this gene include identical protein binding and protein kinase activity. An important paralog of this gene is PLK1.

UniProtKB/Swiss-Prot for PLK4 Gene

  • Serine/threonine-protein kinase that plays a central role in centriole duplication. Able to trigger procentriole formation on the surface of the parental centriole cylinder, leading to the recruitment of centriole biogenesis proteins such as SASS6, CENPJ/CPAP, CCP110, CEP135 and gamma-tubulin. When overexpressed, it is able to induce centrosome amplification through the simultaneous generation of multiple procentrioles adjoining each parental centriole during S phase. Phosphorylates Ser-151 of FBXW5 during the G1/S transition, leading to inhibit FBXW5 ability to ubiquitinate SASS6. Its central role in centriole replication suggests a possible role in tumorigenesis, centrosome aberrations being frequently observed in tumors. Also involved in deuterosome-mediated centriole amplification in multiciliated that can generate more than 100 centrioles. Also involved in trophoblast differentiation by phosphorylating HAND1, leading to disrupt the interaction between HAND1 and MDFIC and activate HAND1. Phosphorylates CDC25C and CHEK2.
