9531538-2	1998	U2AF binds the intron pyrimidine tract between the branchpoint and the 3" splice site and recruits U2 snRNP to the branch site at an early step in spliceosome assembly.	pyrimidine	22-32	U2 small nuclear riboprotein auxiliary factor 38	Drosophila melanogaster	0-4	
9632785-2	1998	U2AF binds site specifically to the intron pyrimidine tract between the branchpoint and the 3" splice site and targets U2 snRNP to the branch site at an early step in spliceosome assembly.	pyrimidine	43-53	U2 small nuclear riboprotein auxiliary factor 38	Drosophila melanogaster	0-4	
9632785-7	1998	The site-specific pyrimidine tract binding activity of the U2AF heterodimer has previously been assigned to hU2AF65.	pyrimidine	18-28	U2 small nuclear riboprotein auxiliary factor 38	Drosophila melanogaster	59-63	
9632785-10	1998	When the Drosophila small-subunit homolog (dU2AF38) was complexed with the large-subunit (dU2AF50) pyrimidine tract, RNA binding activity increased 20-fold over that of free dU2AF50.	pyrimidine	99-109	U2 small nuclear riboprotein auxiliary factor 38	Drosophila melanogaster	43-50
