A catalogue of splice junction sequences

TL;DR: The sequence CAAG/GTAGAGT was found to be a consensus of 139 exon-intron boundaries (or donor sequences) and (TC)nNCTAG/G was found of 130 intron-exon boundaries ( or acceptor sequences).

Abstract: Splice junction sequences from a large number of nuclear and viral genes encoding protein have been collected. The sequence CAAG/GTAGAGT was found to be a consensus of 139 exon-intron boundaries (or donor sequences) and (TC)nNCTAG/G was found to be a consensus of 130 intron-exon boundaries (or acceptor sequences). The possible role of splice junction sequences as signals for processing is discussed.

Drosophila tissues with different metamorphic responses to ecdysone express different ecdysone receptor isoforms
TL;DR: This work uses isoform-specific monoclonal antibodies to show that at the onset of metamorphosis different ecdysone target tissues express different isoform combinations in a manner consistent with the proposition that the different metamorphic responses of these tissues require different combinations of the EcR isoforms.

mec-3, a homeobox-containing gene that specifies differentiation of the touch receptor neurons in C. elegans
Jeffrey C. Way,Martin Chalfie +1 more
TL;DR: The mec-3 gene is cloned by transposon tagging and it is shown that a meC-3 mutant can be rescued by germ line transformation using a 5.6 kb genomic DNA fragment.

Motheaten and viable motheaten mice have mutations in the haematopoietic cell phosphatase gene.
TL;DR: This work has shown that the basic defect in these mice involves lesions in the gene which encodes haematopoietic cell phosphatase (HCP), and these mice provide excellent models for investigating the roles of phosphatases in haem atopoiesis and the nature of the genetic and cellular events linking impaired haematography to severe immunodeficiency and expression of systemic autoimmunity.

Identification of a Gene (GPR30) with Homology to the G-Protein-Coupled Receptor Superfamily Associated with Estrogen Receptor Expression in Breast Cancer
TL;DR: The pattern of expression of GPCR-Br indicates that this receptor may be involved in physiologic responses specific to hormonally responsive tissues.

The U1 small nuclear RNA-protein complex selectively binds a 5' splice site in vitro.
TL;DR: The ability of purified U1 small nuclear RNA-protein complexes (U1 snRNPs) to bind in vitro to two RNAs transcribed from recombinant DNA clones by bacteriophage T7 RNA polymerase is studied.

Are snRNPs involved in splicing
TL;DR: Several lines of evidence are presented that suggest a direct involvement of snRNPs in the splicing of hnRNA molecules, including the observation that the nucleotide sequence at the 5′ end of U1 RNA exhibits extensive complementarity to those across splice junctions in hn RNA molecules.

Ovalbumin gene: evidence for a leader sequence in mRNA and DNA sequences at the exon-intron boundaries.
TL;DR: Selected regions of cloned EcoRI fragments of the chicken ovalbumin gene have been sequenced, and a previously unreported interruption in the DNA sequences coding for the 5' nontranslated region of the messenger has been discovered.

Sequence of the human insulin gene

TL;DR: A comparison of the human with the rat insulin genes indicates potential regulatory regions in the DNA segment preceding the gene and suggests that the ancestral form of the insulin gene had two intervening sequences.

Cloned human and mouse kappa immunoglobulin constant and J region genes conserve homology in functional segments.
TL;DR: The procedure to clone the human kappa chain genes in both germline and rearranged configurations is described and four human J regions are identified that are much more stringently conserved throughout their coding sequences than are the C region genes.
