U1 spliceosomal RNA
U1 spliceosomal RNA (U1 snRNA) is the small nuclear RNA of the U1 snRNP that base-pairs the 5′ splice site (consensus CAG|GUAAGU) to initiate spliceosome assembly, and via U1 telescripting suppresses premature intronic polyadenylation.
U2
U2: Irish rock band formed in Dublin, 25 September 1976 (Bono, The Edge, Adam Clayton, Larry Mullen Jr.), known for The Joshua Tree, 22 Grammys, and the 2026 album Carnaval De Luz.
U2 360° Tour
The U2 360° Tour was a 2009 to 2011 worldwide stadium tour by the Irish rock band U2, the highest-grossing concert tour of all time at its close.
U2 discography
U2 discography: the Irish rock band's 16 studio albums from Boy (1980) to Carnaval De Luz (2026), plus the Passengers side project Original Soundtracks 1, live albums like Under a Blood Red Sky, compilations, and the 2014 iTunes-released Songs of Innocence.
U2 spliceosomal RNA
U2 spliceosomal RNA (U2 snRNA) is the small nuclear RNA of the U2 snRNP that base pairs the pre-mRNA branch site, bulges the branch point adenosine, and with U6 forms the spliceosome's catalytic core; human U2 carries a conserved GTAG motif and its mutations drive cancer.
U212 NFS submarine
The U212 NFS (Near Future Submarine) is a class of four diesel-electric attack submarines built by Fincantieri for the Italian Navy, derived from the U212A design.
U23 Cross-Country World Cup
The U23 Cross-Country World Cup is a FIS season-long under-23 classification within the senior Cross-Country World Cup, with separate men's and women's standings; recent champions include Edvin Anger and Lars Heggen.
U266B1
U266B1 (U266, U-266; CVCL_0566, ATCC TIB-196) is a human IgE lambda-secreting B lymphocyte myeloma cell line established in 1970 from a 53-year-old male patient, used widely in multiple myeloma and immunology research.
U2AF1
U2AF1 (U2AF35) encodes the small subunit of the U2AF splicing factor that binds the 3' splice site AG dinucleotide; recurrent S34 and Q157 hotspot mutations drive myelodysplastic syndromes and leukemias with altered splice-site preference and poor prognosis.
U2AF2
U2AF2 (U2AF65) is a human chromosome 19q13.42 gene encoding the 65-kDa large subunit of the U2AF splicing factor, which binds intron polypyrimidine tracts to define 3' splice sites; de novo variants cause neurodevelopmental disorder and overexpression marks poor cancer prognosis.
U2OS
U2OS (U-2 OS), human osteosarcoma cell line from a 15-year-old girl's tibia, established 1964 by Ponten and Saksela; first human osteosarcoma line, p53 wild-type, epithelial-like morphology, standard model for DNA damage and imaging research.
U4 spliceosomal RNA
U4 spliceosomal RNA (U4 snRNA; genes RNU4-1, RNU4-2) is a 142-nt human small nuclear RNA that pairs with U6 to keep the spliceosome inactive until Brr2 unwinds the duplex; RNU4-2 variants cause neurodevelopmental disease.
U6 spliceosomal RNA
U6 spliceosomal RNA (U6 snRNA) is one of five small nuclear RNAs forming the spliceosome, which removes introns from pre-mRNA; it forms much of the spliceosome's catalytic core.
U7 small nuclear RNA
U7 snRNA (RNU7-1) is a 57-70 nt non-coding RNA forming the U7 snRNP with Lsm10/Lsm11 Sm proteins; it guides CPSF73 cleavage of replication-dependent histone pre-mRNA 3' ends and, engineered as U7 SmOPT, serves DMD exon-skipping and ADAR RNA-editing therapies.
U96
U96 is a German electronic dance act from Hamburg, formed by producer Alex Christensen with the production team Matiz, best known for the chart-topping 1991 techno single "Das Boot".
Ua-ogrere Mons
Ua-ogrere Mons (Ua ogrere Mons) is a 200 km-diameter mountain on Venus at 40.5°N, 117°E, named in 1997 for a Kivai ancestor deity of New Guinea.
UA022 (KRAS G12D inhibitor)
