alternative products:Additional isoforms seem to exist,function:Necessary for the ATP-dependent first step of spliceosome assembly. Binds to the intron branch point sequence (BPS) 5'-UACUAAC-3' of the pre-mRNA. May act as transcription repressor.,PTM:Phosphorylation on Ser-20 interferes with U2AF2 binding and spliceosome assembly. Isoform 6 is phosphorylated on Ser-463.,similarity:Belongs to the BBP/SF1 family.,similarity:Contains 1 CCHC-type zinc finger.,similarity:Contains 1 KH domain.,subunit:Binds U2AF2. Interacts with U1 snRNA. Binds EWSR1, FUS and TAF15.,tissue specificity:Detected in lung, ovary, adrenal gland, colon, kidney, muscle, pancreas, thyroid, placenta, brain, liver and heart.,
