Plk4 Gene Summary [Rat]
Predicted to enable identical protein binding activity and protein serine/threonine kinase activity. Predicted to be involved in several processes, including organelle assembly; positive regulation of centriole replication; and trophoblast giant cell differentiation. Predicted to be located in several cellular components, including XY body; deuterosome; and microtubule organizing center. Predicted to be part of procentriole replication complex. Predicted to be active in nucleus. Biomarker of diabetic retinopathy. Human ortholog(s) of this gene implicated in microcephaly and chorioretinopathy 2. Orthologous to human PLK4 (polo like kinase 4). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Plk4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
