Short name: Isy1_sf

Overlapping entries

Description

This entry includes yeast Isy1 and it's homologues from plants and animals. In budding yeast, Isy1 is part of the NineTeen Complex (NTC), which is involved in spliceosome activation by specifying the interaction of U5 and U6 with pre-mRNA for their stable association with the spliceosome after U4 dissociation [PMID: 16540691]. The S. pombe homologue is known as Cwf12.
