RT neoformans.";
RL Science 307:1321-1324(2005).
CC -!- FUNCTION: Necessary for the splicing of pre-mRNA. Has a role in the
CC recognition of the branch site (5'-UACUAAC-3'), the pyrimidine tract
CC and the 3'-splice site at the 3'-end of introns (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the BBP/SF1 family. {ECO:0000305}.
