Term:U12-type catalytic step 2 spliceosome
go back to main search page
Accession:GO:0071018 term browser browse the term
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.
Synonyms:exact_synonym: minor catalytic step 2 spliceosome
 narrow_synonym: AT-AC catalytic step 2 spliceosome;   mammalian U12-type spliceosomal complex C;   mammalian U12-type spliceosomal complex C1;   yeast U12-type spliceosomal complex A2-2
