Pre-mRNA splicing occurs in two sequential
transesterification steps. The protein encoded by this gene is a
splicing factor that has been found to be essential during the
second catalytic step in the pre-mRNA splicing process. It
associates with the spliceosome and contains a zinc knuckle motif
that is found in other splicing factors and is involved in
protein-nucleic acid and protein-protein interactions. [provided by
