12630912-1	2003	Substitution of Cys-634 in the extracellular domain of the Ret tyrosine kinase receptor causes its dimerization and activation of its transforming potential.	Cysteine	16-19	ret proto-oncogene	Homo sapiens	59-62	
12630912-2	2003	To gain further insight into the molecular basis leading to Ret activation we purified a mutant protein consisting of the entire ectodomain of the Ret carrying a Cys-634-->Tyr substitution (EC-Ret(C634Y)).	Cysteine	162-165	ret proto-oncogene	Homo sapiens	147-150
