Show all Align All Isoform A identifier: Embryonic lethal, or in the case of viable and ostensibly hypomorphic alleles, displays poor jumping and flying ability plus aberrant visual physiology and behavior. ELAV has been implicated in the nuclear processing of transcripts of three genes: Belote for the D. Elav ensures that the correct alternatively spliced protein isoforms of certain genes are generated in neurons.

Lethal “focusing” in these mosaics suggests influence of gene on derivatives dgosophila ventral blastoderm. The amount of n-arm is reduced in Elav-deficient eye discs, and in the ectopically expressing wing discs expression of n-arm is clearly induced.

xrosophila The gels were dried onto gel blot paper and exposed overnight on a PhosphorImager screen Molecular Dynamics. C Four deletions were made in the nt RNA Quantification of transgene expression in dissected muscle tissue using quantitative PCR qPCR shows that both promoters drive robust transgene expression GFP signalbut only the native promoter drives expression of extension sequences.

Sequence analysis confirmed proper splice site usage for the default and neural-specific spliced transcripts data not shown. Further studies will be needed to address these questions. Lethal elzv in elav 1 mosaics suggests influence of gene on derivatives of ventral blastoderm.

Terms Based on Predictions or Assertions 1 term. Finally, it was demonstrated that ubiquitous Elav has regulatory capacity, since derepressed Elav can stabilize an Elav-responsive sensor.


ELAV has been implicated in the nuclear processing of transcripts of three genes: Interactive Fly – A cyberspace guide to Drosophila development and metazoan evolution. Cellular Component 2 terms.

Protein elav

This is similar to the scenario for the alternative splicing of traor the Sex-lethal autoregulated intron, in which Sxl targets the default PPT Sosnowski et al. Homyk and Pye,White et al.

In vitro transcription reactions with T3 RNA polymerase were performed using standard protocols. In the latter case, only the promoter driving the extended isoform contains paused Pol II Oktaba, Elav is necessary to drosophula Ewg protein expression in Elav-null eye imaginal disc clones and Elav is sufficient for Ewg expression in wing disc imaginal tissue after ectopic expression. Ub—GFP expresses green fluorescent ellav under the control of the ubiquitin promoter. Could ELAV additionally regulate polyadenylation of the default transcript?

An antibody specifically recognizing the neural-specific Nrg also recognizes a protein in the D. Reviewed – Annotation score: Studies on factors that influence neuronal alternative splicing have revealed that similar to other tissue-specific splicing, certain ubiquitously present RNA-binding proteins are important to splicing regulation for reviews, see Horowitz and Krainer ; Grabowski A nt block of poly U -rich homology Fig.

To confirm that 3′ extension depends on native promoter regions of extended genes, a construct bearing the fully extended brat 3′ UTR downstream of GFP was also tested, using three different promoters: Database for complete collections of gene phylogenies More Mus musculus laboratory mouse 5.


Click to get a list of regulatory features enhancers, TFBS, etc. Increased interaction between paused promoters and termination regions might help promote 3′ extension, for example, by bringing ELAV to the promoter via gene looping.

With the exception of one subclass within this family, HuA, their expression is largely restricted to the nervous system Okano and Darnell See Gelbart and Emmert, for analysis details and data files for all genes.

In independent experiments using an HCI probe I, intronthe unspliced CNVwhich would be seen as the HC-protected species in the figure above, is present, but in very low amounts data not shown.
