Summary: Enables IkappaB kinase activity and protein phosphatase binding activity. Involved in canonical NF-kappaB signal transduction; cell surface receptor signaling pathway; and peptidyl-serine phosphorylation. Acts upstream of or within B cell homeostasis; positive regulation of cation channel activity; and positive regulation of sodium ion transport. Located in cytoplasmic side of plasma membrane. Part of CD40 receptor complex and IkappaB kinase complex. Is expressed in several structures, including cerebral cortex; genitourinary system; heart; and musculature. Used to study immunodeficiency 15A. Human ortholog(s) of this gene implicated in several diseases, including breast cancer; combined immunodeficiency (multiple); liver cancer; prostate cancer (multiple); and type 2 diabetes mellitus. Orthologous to human IKBKB (inhibitor of nuclear factor kappa B kinase subunit beta). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
