The shows proteins in white and the three snRNAs in colour (U4, U5, and U6).
Focusing reveals extensive base pairing between the U4 and U6 snRNAs.
The U2 snRNP highlighted in blue in this view. The U1 snRNP binds to the U2snRNP. Both interactions lead to extensive conformational change and activation of the spliceosome.
