CC -!- FUNCTION: General splicing factor. Can promote splice site selection in
CC vitro presumably by antagonizing the effects of the A1 heterogeneous
CC nuclear ribonucleoprotein. May have an essential function during early
CC plant development. {ECO:0000269|PubMed:10215626}.
CC -!- SUBUNIT: Component of the spliceosome. Interacts with SNRNP35, RS2Z33,
CC SR34, CYP59, CYP63 and CYP95. The binding to CYP63 is phosphorylation-
CC dependent (PubMed:15166240). Interacts with MOS14 (PubMed:21738492).
