9335504-4	1997	Phosphorylation occurs at specific serines within the region linking the inhibitory and effector domains of Smad1, and is catalysed by the Erk family of mitogen-activated protein kinases.	Serine	35-42	SMAD family member 1	Homo sapiens	108-113

9335504-5	1997	In contrast to the BMP-stimulated phosphorylation of Smad1, which affects carboxy-terminal serines and induces nuclear accumulation of Smad1, Erk-mediated phosphorylation specifically inhibits the nuclear accumulation of Smad1.	Serine	91-98	SMAD family member 1	Homo sapiens	53-58
