Guanylate kinase
From Proteopedia
Guanylate kinase (GK) catalyzes the transfer of phosphate from GMP to GDP using ATP as a phosphate source. GK is essential for recycling GMP and cGMP. GK also forms a domain in the membrane-associated GK (MAGUK) which functions in mitotic spindle orientation and cell adhesion. There is a single mutation in GK which converts it to a GK domain. The GK domain has no catalytic activity. The MAGUK contain PDZ, WW, SH3 and GK domains.
