  • GT-AG precatalytic spliceosome
  • major precatalytic spliceosome
  • mammalian U2-type spliceosomal complex B
  • mammalian U2-type spliceosomal complex B1
  • yeast U12-type spliceosomal complex A2-1
Definition
A spliceosomal complex that is formed by the recruitment of the preassembled U4/U6.U5 tri-snRNP to the 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 U1, U2 and U4/U6.U5 snRNPs. (2)
