19850744-6	2009	In the presence of ATRA, lysine 166 (K166) and K171 of RARA were modified at a physiological concentration of SUMO-2, whereas in the absence of ATRA, K399 was the only site that was modified, but at a higher SUMO-2 concentration.	trans-1,4-dibromo-2-butene	47-51	retinoic acid receptor, alpha	Mus musculus	55-59

18924190-1	2008	Enantioselective allylic alkylation with an organomagnesium reagent catalyzed by copper thiophene carboxylate (CuTC) was carried out on difunctionalized substrates, such as commercially available 1,4-dichloro-2-butene and 1,4-dibromo-2-butene, and on similar compounds of higher substitution pattern of the olefin for the formation of all-carbon chiral quaternary centers.	trans-1,4-dibromo-2-butene	222-242	cutC copper transporter	Homo sapiens	111-115
16018680-3	2005	The strategy was based on the dialkylation of a glycine Schiff base using trans-1,4-dibromo-2-butene as an electrophile to produce racemic vinyl-ACCA, which was subsequently resolved using a readily available, inexpensive esterase enzyme (Alcalase 2.4L).	trans-1,4-dibromo-2-butene	74-100	G protein-coupled receptor 3	Homo sapiens	145-149
