Our Abpromise guarantee covers the use of ab2642 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use a concentration of 10 µg/ml.|
|Flow Cyt||Use a concentration of 10 µg/ml.|
|WB||Use a concentration of 1 - 3 µg/ml. Detects a band of approximately 110 kDa (predicted molecular weight: 109 kDa).Can be blocked with Human PLK4 peptide (ab22924).|
FunctionSerine/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, CP110, 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. Its central role in centriole replication suggests a posible role in tumorigenesis, centrosome aberrations being frequently observed in tumors. Also involved in trophoblast differentiation by phosphorylating HAND1, leading to disrupt the interaction between HAND1 and MDFIC and activate HAND1. Phosphorylates CDC25C and CHEK2/CHK2.
Sequence similaritiesBelongs to the protein kinase superfamily. Ser/Thr protein kinase family. CDC5/Polo subfamily.
Contains 1 POLO box domain.
Contains 1 protein kinase domain.
modificationsUbiquitinated; leading to its degradation by the proteasome.
Tyrosine-phosphorylated by TEC.
Cellular localizationCytoplasm > cytoskeleton > centrosome > centriole. Nucleus > nucleolus. Cleavage furrow. Associates with centrioles throughout the cell cycle. According to PubMed:16244668, it is not present at cleavage furrows.

Immunofluorescence analysis of paraformaldehyde fixed HeLa cells staining PLK4. Cells were permeabilized with 0.15% Triton. Samples were incubated with primary anitbody for 1 hour at 10µg/ml. An Alexa Fluor 488 was used as the secondary antibody. DAPI was used as a nuclear counterstain. Unimmunized goat IgG (10µg/ml) was used as the negative control.
