Subunit Structure: Homodimer (By similarity). Interacts with CEP152 (via N-terminus). Interacts with CEP78; this interaction may be important for proper PLK4 localization to the centriole and PLK4-induced overduplication of centrioles (PubMed:27246242).
Post-translational Modifications: Acetylation by KAT2A and KAT2B impairs kinase activity by shifting the kinase to an inactive conformation. Ubiquitinated; leading to its degradation by the proteasome.Tyrosine-phosphorylated by TEC.
Similarity: Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CDC5/Polo subfamily.
NCBI and Uniprot Product Information
Predicted: 109 kDa
NCBI Description
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]
Uniprot Description
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. Required for the recruitment of STIL to the centriole and for STIL-mediated centriole amplification (PubMed:22020124).

Product Notes
The PLK4 plk4 (Catalog #AAA9608571) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The PLK4 Antibody reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's PLK4 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), ELISA (EIA). WB: 1:1000-3000. Researchers should empirically determine the suitability of the PLK4 plk4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "PLK4, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
