Rps6kb1 Gene Summary [Rat]
Enables several functions, including ATP binding activity; PDZ domain binding activity; and protein phosphatase 2A binding activity. Involved in several processes, including long-term memory; positive regulation of skeletal muscle tissue growth; and skeletal muscle atrophy. Located in cell surface and perinuclear region of cytoplasm. Is active in postsynapse. Biomarker of several diseases, including autosomal dominant polycystic kidney disease; hyperinsulinism; muscular atrophy; obesity; and primary biliary cholangitis. Orthologous to human RPS6KB1 (ribosomal protein S6 kinase B1). [provided by Alliance of Genome Resources, Jul 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 Rps6kb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
