CC -!- FUNCTION: Regulatory subunit of casein kinase II/CK2. As part of the
CC kinase complex regulates the basal catalytic activity of the alpha
CC subunit a constitutively active serine/threonine-protein kinase that
CC phosphorylates a large number of substrates containing acidic residues
CC C-terminal to the phosphorylated serine or threonine (By similarity).
CC Participates in Wnt signaling (By similarity).
CC {ECO:0000250|UniProtKB:P67870, ECO:0000250|UniProtKB:P67871}.
CC -!- SUBUNIT: Casein kinase II/CK2 is a tetramer composed of an alpha
CC subunit, an alpha' subunit and two beta subunits. The beta subunit
CC dimerization is mediated by zinc ions. Interacts with CD163. Also
CC component of a CK2-SPT16-SSRP1 complex composed of SSRP1, SUPT16H,
CC CSNK2A1, CSNK2A2 and CSNK2B, the complex associating following UV
CC irradiation (By similarity). Interacts with DYNLT2. Interacts with
CC MUSK; mediates phosphorylation of MUSK by CK2. Interacts with FGF1;
CC this interaction is increased in the presence of FIBP, suggesting a
CC possible cooperative interaction between CSNKB and FIBP in binding to
CC FGF1 (By similarity). {ECO:0000250|UniProtKB:P67870}.
CC -!- PTM: Phosphorylated by alpha subunit. Also a component of a CK2-SPT16-
CC SSRP1 complex composed of SSRP1, SUPT16H, CSNK2A1, CSNK2A2 and CSNK2B,
CC the complex associating following UV irradiation (By similarity).
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the casein kinase 2 subunit beta family.
CC {ECO:0000305}.
