ID 2.7.11.9 DE [Goodpasture-antigen-binding protein] kinase. AN Goodpasture antigen-binding protein kinase. AN GPBPK. AN GPBP kinase. CA (1) L-seryl-[Goodpasture antigen-binding protein] + ATP = O-phospho-L- CA seryl-[Goodpasture antigen-binding protein] + ADP + H(+). CA (2) L-threonyl-[Goodpasture antigen-binding protein] + ATP = O-phospho-L- CA threonyl-[Goodpasture antigen-binding protein] + ADP + H(+). CC -!- This serine/threonine kinase specifically binds to and phosphorylates CC the N-terminal region of the human Goodpasture antigen, which is CC located on the alpha3 chain of collagen IV and is involved in CC autoimmune disease. CC -!- Formerly EC 2.7.1.37. //
