Vrk1 Gene Summary [Rat]
Predicted to enable several functions, including histone binding activity; histone kinase activity; and nucleosomal DNA binding activity. Predicted to be involved in several processes, including Cajal body organization; Golgi disassembly; and positive regulation of protein localization to chromatin. Predicted to act upstream of or within protein autophosphorylation. Predicted to be located in several cellular components, including Golgi stack; chromatin; and nuclear lumen. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in autosomal recessive distal hereditary motor neuronopathy 10 and pontocerebellar hypoplasia type 1A. Orthologous to human VRK1 (VRK serine/threonine kinase 1). [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 Vrk1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
