2b0g is a 1 chain structure with sequence from Drosophila melanogaster. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
SNRPA_DROME Binds stem loop II of U1 snRNA. It is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP (By similarity). Plays a role in regulating sex-lethal splicing.
