CSNK2B

Function

Regulatory subunit of casein kinase II/CK2. As part of the kinase complex regulates the basal catalytic activity of the alpha subunit a constitutively active serine/threonine-protein kinase that phosphorylates a large number of substrates containing acidic residues C-terminal to the phosphorylated serine or threonine (PubMed:11239457, PubMed:16818610). Participates in Wnt signaling (By similarity).

Involvement in disease

Poirier-Bienvenu neurodevelopmental syndrome

POBINDS

An autosomal dominant neurodevelopmental disorder characterized by onset of seizures in infancy, developmental delay, impaired intellectual development, and poor or absent speech.

None

The disease is caused by variants affecting the gene represented in this entry.

Post-translational modifications

Phosphorylated by alpha subunit.
