Automatically generated summary

See sections below for more information
The gene small nuclear RNA U1 at 95Ca is referred to in FlyBase by the symbol Dmel\snRNA:U1:95Ca (CR31341, FBgn0004185). It is a snRNA_gene from Drosophila melanogaster. Its molecular function is unknown. Based on sequence similarity, it is predicted to be involved in the biological process: mRNA splicing, via spliceosome. 2 alleles are reported. No phenotypic data is available. It has one annotated transcript. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of low expression to a trough of no expression detected. Peak expression observed within 00-06 hour embryonic stages, in adult female stages. CAVEAT: These RNA-Seq temporal profiles depend upon RNA-Seq reads that are uniquely placed in the genome. For this reason, genes such as histones, Stellates and many classes of RNA genes that are present in multiple exact or near exact copies in the genome, expression levels may be reported as much lower than their true values. Summary of FlyAtlas Anatomical Expression Data: No FlyAtlas data available because no Affy2 ProbeSet aligns to an exon of snRNA:U1:95Ca. Comments on Affy2 ProbeSet: No relevant information because no Affy2 ProbeSet aligns to an exon of snRNA:U1:95Ca. Gene sequence location is 3R:19685189..19685352.

Peak expression observed within 00-06 hour embryonic stages, in adult female stages. CAVEAT: These RNA-Seq temporal profiles depend upon RNA-Seq reads that are uniquely placed in the genome.

New annotation (CR31341) in release 3 of the genome annotation.
Coordinates (on date of analysis) on AE003745:55799..55636.
Variation of a microsatellite within the snRNA:U1:95Ca locus has been studied in North American populations of D.melanogaster.
Basal snRNA:U1:95Ca transcription in vitro requires DNA sequences upstream of position -32; PSEA, PSEB and the initiation site for transcription in vitro. Spacing between PSEA and PSEB is crucial for efficient expression in vitro. snRNA:U1:95Ca transcription in vitro requires Tbp.
snRNA:U1:95Ca has been cloned and sequenced.
