17963781-3	2007	Here we report that the alpha-NH(2) group of the N terminus and the epsilon-NH(2) groups of internal lysine residues 116, 118 and 269 (K116, K118 and K269) of Smad1 are ubiquitin acceptor sites mediated by the carboxyl terminus of Hsc70-interacting protein (CHIP).	Lysine	101-107	SMAD family member 1	Homo sapiens	159-164	
10846168-4	2000	This basic motif (Lys(40-)Lys-Leu-Lys-Lys(44)), conserved among all the pathway-specific Smad proteins, is required for Smad 3 nuclear import in response to ligand.	Lysine	18-21	SMAD family member 1	Homo sapiens	89-93
