32343311-6	2020	When the U2AF heterodimer is bound to a strong, uridine-rich splice site, U2AF2 switches to a lower FRET value characteristic of an open, side-by-side arrangement of the RRMs.	Uridine	48-55	U2 small nuclear RNA auxiliary factor 2	Homo sapiens	74-79	
16818232-2	2006	Since Py tracts are relatively poorly conserved in higher eukaryotes, U2AF(65) is faced with the problem of specifying uridine-rich sequences, yet tolerating a variety of nucleotide substitutions found in natural Py tracts.	Uridine	119-126	U2 small nuclear RNA auxiliary factor 2	Homo sapiens	70-77	
21074620-7	2011	The complementary aspects of combining NMR and SAS data for studying multi-domain proteins, i.e. where weakly interacting domains are connected by flexible linkers, are illustrated with the structural analysis of the tandem RNA recognition motif (RRM) domains (RRM1-RRM2) of the human splicing factor U2AF65 bound to a nine-uridine (U9) RNA oligonucleotide.	Uridine	324-331	U2 small nuclear RNA auxiliary factor 2	Homo sapiens	301-307	
18549497-4	2008	The PY tract is a uridine-rich region at the 3" end of introns that acts as a binding site for U2AF65, a key factor in splicing machinery recruitment.	Uridine	18-25	U2 small nuclear RNA auxiliary factor 2	Homo sapiens	95-101	
16818232-3	2006	To better understand these apparently contradictory RNA binding characteristics, the X-ray structure of the U2AF(65) RNA binding domain bound to a Py tract composed of seven uridines has been determined at 2.5 A resolution.	Uridine	174-182	U2 small nuclear RNA auxiliary factor 2	Homo sapiens	108-116	
7761834-3	1995	The uridine-rich degenerate sequences selected by U2AF65 are similar to those present in the diverse array of natural metazoan Py-tracts.	Uridine	4-11	U2 small nuclear RNA auxiliary factor 2	Homo sapiens	50-56	
12558503-2	2003	We report that U2AF(65) can also promote the recruitment of U1 snRNP to weak 5" splice sites that are followed by uridine-rich sequences.	Uridine	114-121	U2 small nuclear RNA auxiliary factor 2	Homo sapiens	15-22	
35524551-8	2022	Moreover, enhanced UV-crosslinking and immunoprecipitation of endogenous U2AF2 in human erythroleukemia cells showed uridine-sensitive binding sites, with lower sequence conservation at the central nucleotide positions of otherwise uridine-rich, U2AF2-bound splice sites.	Uridine	117-124	U2 small nuclear RNA auxiliary factor 2	Homo sapiens	73-78
