9139732-4	1997	Notably, two neighboring pRB phosphate acceptors, threonine 821 and threonine 826, which have previously been implicated in the regulation of LXCXE protein binding, are phosphorylated by different CDKs.	Threonine	50-59	cyclin dependent kinase 2	Homo sapiens	197-201	
9139732-4	1997	Notably, two neighboring pRB phosphate acceptors, threonine 821 and threonine 826, which have previously been implicated in the regulation of LXCXE protein binding, are phosphorylated by different CDKs.	Threonine	68-77	cyclin dependent kinase 2	Homo sapiens	197-201	
9139732-5	1997	We demonstrate that phosphorylation by either CDK2-cyclin A, which phosphorylates T821, or CDK4-cyclin D1, which phosphorylates threonine 826, can disable pRB for subsequent binding of an LXCXE protein.	Threonine	128-137	cyclin dependent kinase 2	Homo sapiens	46-50
