This Polo box (PB) domain is found in Polo-like kinase 4 (Plk4) present in Drosophila melanogaster. Plk4 is a conserved component in the duplication pathway of centrioles which is needed to prevent chromosomal instability. Plk4 localizes to centrioles in M/G1. Structural analysis reveals two tandem, homodimerized polo boxes, PB1-PB2, that form a winged architecture. This domain is PB2, together with PB1 Pfam:PF18190 , they are required for binding the centriolar protein Asterless (Asl) as well as robust centriole targeting. In other words, PB1-PB2 cassette collectively binds Asl and affords robust centriole localization, optimally positioning the kinase domain for trans-autophosphorylation [1].	Domain

This domain is found in Polo-like kinase 4 (Plk4) present in Drosophila melanogaster. Plk4 is a conserved component in the duplication pathway of centrioles which is needed to prevent chromosomal instability. The domain is Polo Box 1 (PB1) and has a pseudo-symmetric dimerization interface across PB1-PB1 [1].	Domain
