Structure of U2AF65 variant with BrU3 DNA
Template:ABSTRACT PUBMED 23376934
Function
[U2AF2_HUMAN] Necessary for the splicing of pre-mRNA. Induces cardiac troponin-T (TNNT2) pre-mRNA exon inclusion in muscle. Regulates the TNNT2 exon 5 inclusion through competition with MBNL1. Binds preferentially to a single-stranded structure within the polypyrimidine tract of TNNT2 intron 4 during spliceosome assembly. Required for the export of mRNA out of the nucleus, even if the mRNA is encoded by an intron-less gene. Represses the splicing of MAPT/Tau exon 10.[1] [2] [3]
About this Structure
3vaf is a 4 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
