compound source
Molecule: U1 Snrna Stem-Loops 1 And 2 (55-Mer)
Chain: V
Engineered: Yes
Other_details: Rna Is A Dumbell-Shaped Fusion Of U1 Snrna S And The Apical Part Of U1 Snrna Stem-Loop 2 Joined By A 3 B Linker. Transcribed By T7 Rna Polymerase From A Linearised Template.;
Synthetic: Yes
Organism_scientific: Homo Sapiens
Organism_common: Human
Organism_taxid: 9606
Other_details: See Compound Details.

Molecule: U1 Small Nuclear Ribonucleoprotein A,U1 Small Nuc Ribonucleoprotein 70 Kda;
Chain: B
Synonym: U1a,Snrnp70
Engineered: Yes
Mutation: Yes
Other_details: Both This Protein And U1-70k Are Expressed T A Fusion Protein. The C-Terminus Of U1-A And The Linker Pep Disordered In The Structure. The Two Proteins Have Been Giv Separate Chain Identifiers So That Their Normal Numbering I Preserved., U1-A And This Protein Are Expressed Together As Protein. The C-Terminus Of U1-A And The Linker Peptide Are In The Structure. The Two Proteins Have Been Given Separate Identifiers So That Their Normal Numbering Is Preserved.
