- U1 snRNP - UMD
U1 snRNP is the first to bind the splicing complex to form the commitment complex during spliceosome assembly The branch-point bridging protein then binds to a snRNP of U1 and the spliceosome cycle proceeds to the A complex

Each letter marks a definite structure Letter A marks the thread, to which the ribosome is attached This thread is the base of the translation Letter B marks the structure, which is bonded with Gly and is located inside the ribosome Letter C marks the structure, in which the translation happens
- U1 spliceosomal RNA - Wikipedia
In humans, the U1 spliceosomal RNA is 164 bases long, forms four stem-loops, and possesses a 5'-trimethylguanosine five-prime cap Bases 3 to 10 are a conserved sequence that base-pairs with the 5' splice site of introns during RNA splicing, and bases 126 to 133 form the Sm site, around which the Sm ring is assembled
- RCSB PDB - 3CW1: Crystal Structure of Human Spliceosomal U1 snRNP
Human spliceosomal U1 small nuclear ribonucleoprotein particles (snRNPs), which consist of U1 small nuclear RNA and ten proteins, recognize the 5' splice site within precursor messenger RNAs and initiate the assembly of the spliceosome for intron excision
- U1A RNA Spliceosomal Protein - earth. callutheran. edu
Pre-mRNA splicing reactions are catalyzed by the concerted action of 5 small nuclear ribonucleoproteins (snRNPs) The U1 snRNP consists of a 164 nucleotide RNA (U1 snRNA), eight core proteins shared by all snRNPs, and three U1-specific proteins
- AT-U1 - Addgene
Plasmid AT-U1 from Dr Amy Palmer's lab contains the insert U1 and is published in Nat Chem Biol 2018 Jul 30 pii: 10 1038 s41589-018-0103-7 doi: 10 1038 s41589-018-0103-7 This plasmid is available through Addgene
- Crystal structure of human U1 snRNP, a small nuclear . . . - eLife
We present two crystal structures of engineered U1 sub-structures, which together reveal at atomic resolution an almost complete network of protein–protein and RNA-protein interactions within U1 snRNP, and show how the 5′ splice site of pre-mRNA is recognised by U1 snRNP
- Crystal structure of human spliceosomal U1 snRNP at 5. 5 Å resolution
Human spliceosomal U1 small nuclear ribonucleoprotein particles (snRNPs), which consist of U1 small nuclear RNA and ten proteins, recognize the 59 splice site within precursor messenger RNAs
