  • mammalian U12-type spliceosomal complex B
  • mammalian U12-type spliceosomal complex B1
  • minor precatalytic spliceosome
  • yeast U12-type spliceosomal complex A2-1
Definition
A spliceosomal complex that is formed by the recruitment of the preassembled U4atac/U6atac.U5 tri-snRNP to the U12-type prespliceosome. Although all 5 snRNPs are present, the precatalytic spliceosome is catalytically inactive. The precatalytic spliceosome includes many proteins in addition to those found in the U11, U12 and U4atac/U6atac.U5 snRNPs. 16201866
