U12-type catalytic step 2 spliceosome

Term ID
GO:0071018
Synonyms
  • AT-AC catalytic step 2 spliceosome
  • mammalian U12-type spliceosomal complex C
  • mammalian U12-type spliceosomal complex C1
  • minor catalytic step 2 spliceosome
  • yeast U12-type spliceosomal complex A2-2
Definition
A spliceosomal complex that contains the U12, U5 and U6atac snRNPs bound to a splicing intermediate in which the first catalytic cleavage of the 5' splice site has occurred. The precise subunit composition differs significantly from that of the catalytic step 1, or activated, spliceosome, and includes many proteins in addition to those found in the U12, U5 and U6atac snRNPs.
