19711980-6	2009	Apparently, introducing fluorine results in more stable GB1 mutants (Pff > Phe, Hfl > Qfl > Leu, Atb > Abu).	Leucine	101-104	gamma-aminobutyric acid type B receptor subunit 1	Homo sapiens	56-59	
18928314-9	2008	Addition of an Fc domain to this GB1 complex causes a small but defined change in the SH signal when Aladan is incorporated at site Ala(24), but not at Leu(7), consistent with a local conformational change of GB1.	Leucine	152-155	gamma-aminobutyric acid type B receptor subunit 1	Homo sapiens	33-36
