RNA trimethylguanosine cap binding

id: GO:0000341
name: RNA trimethylguanosine cap binding
namespace: molecular_function
type: go
obsolete: False

Description: Interacting selectively and non-covalently with the trimethylguanosine (m(3)(2,2,7)-GTP) group located at the 5' end of some RNA molecules. Such trimethylated cap structures, generally produced by posttranscriptional modification of a 7-methylguanosine cap, are often found on snRNAs and snoRNAs transcribed by RNA polymerase II, but have also be found on snRNAs transcribed by RNA polymerase III. They have also been found on a subset of the mRNA population in some species, e.g. C. elegans.
