Riok2 Gene Summary [Rat]
Predicted to enable ATP binding activity; metal ion binding activity; and protein serine/threonine kinase activity. Predicted to be involved in several processes, including positive regulation of rRNA processing; positive regulation of ribosomal small subunit export from nucleus; and regulation of mitotic metaphase/anaphase transition. Predicted to be located in cytoplasm. Predicted to be part of preribosome, small subunit precursor. Orthologous to human RIOK2 (RIO kinase 2). [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 Riok2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
