Predicted to be involved in generation of catalytic spliceosome for first transesterification step. Predicted to be part of Prp19 complex; U2-type catalytic step 2 spliceosome; and post-mRNA release spliceosomal complex. Expressed in head and tail. Is an ortholog of human XAB2 (XPA binding protein 2).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
