ID 2.7.11.29 DE [low-density-lipoprotein receptor] kinase. AN LDL receptor kinase. AN low-density-lipoprotein kinase. AN low-density lipoprotein receptor kinase. AN low-density-lipoprotein receptor kinase (phosphorylating). CA ATP + L-seryl-[low-density-lipoprotein receptor] = ADP + H(+) + CA O-phospho-L-seryl-[low-density-lipoprotein receptor]. CC -!- Phosphorylates the last serine residue (Ser-833) in the cytoplasmic CC domain of the low-density lipoprotein receptor. CC -!- Casein can also act as a substrate but with lower affinity. CC -!- GTP can act instead of ATP. CC -!- Formerly EC 2.7.1.131. //
