A spliceosomal factor involved in substrate-specific 3′ splice-site recognition and progression through the second catalytic step. Interaction with <Sex-lethal> provides a mechanism of late splicing control.<Splicing regulation at the second catalytic step by Sex-lethal involves 3′ splice site recognition by SPF45 by María José Lallena and others>[Autoregulatory substrate experiments]{ref}
