Accepted name: |
low-density-lipoprotein receptor kinase |
Reaction: |
ATP + [low-density-lipoprotein receptor]-L-serine = ADP + [low-density-lipoprotein receptor]-O-phospho-L-serine |
Other name(s): |
ATP:low-density-lipoprotein-L-serine O-phosphotransferase; LDL receptor kinase; [low-density-lipoprotein] kinase; low-density lipoprotein kinase; low-density-lipoprotein receptor kinase (phosphorylating); STK7 |
Systematic name: |
ATP:[low-density-lipoprotein receptor]-L-serine O-phosphotransferase |
Comments: |
Phosphorylates the last serine residue (Ser-833) in the cytoplasmic domain of the low-density lipoprotein receptor from bovine adrenal cortex. Casein can also act as a substrate but with lower affinity. GTP can act instead of ATP. |
