9224730-7	1997	A six-fold decrease in Csk activity (expressed as Vmax/Km ratio) was achieved due to a threefold increase in its Km and a twofold decrease in its Vmax value within 1 h of incubation with the catalytic subunit of PKA and ATP-Mg.	atp-mg	220-226	C-terminal Src kinase	Homo sapiens	23-26	
11162381-1	2001	Protein tyrosine kinase Csk requires two Mg2+ ions for activity: one magnesium is part of the ATP-Mg complex, and the second free Mg2+ ion is required as an essential activator.	atp-mg	94-100	C-terminal Src kinase	Homo sapiens	24-27
