RT   kinase II.";
RL   Submitted (JUN-1998) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Casein kinases are operationally defined by their
CC       preferential utilization of acidic proteins such as caseins as
CC       substrates. The alpha chain contains the catalytic site. May
CC       participate in Wnt signaling.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
CC         [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC         EC=2.7.11.1;
CC   -!- SUBUNIT: Tetramer of two alpha and two beta chains.
CC   -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC       kinase family. CK2 subfamily. {ECO:0000255|PROSITE-ProRule:PRU00159}.
