Meanings of alternative promoter in inglês

We conclude that Mef2c expression from an alternative promoter in the retina is regulated by NRL.

This isoform is transcribed from an alternative promoter and results in a protein with an amino-terminal extension.

Since the two expression modes are a result of alternative promoter usage, the sex-specific transcripts differ at their 5' ends.

Thus, both alternative promoter usage and differential splicing are in fact operative for the tissue-specific expression of the rat AADC gene.

Molecular heterogeneity in the 5'-region defines four novel Gs alpha cDNA species which are generated either by alternate splicing or by using alternative promoter.

However, the presence of a truncated p16 transcript in methylated cell lines led us to investigate the presence of an alternative promoter or initiation site.

Structural analysis of the rat AADC gene showed that both alternative promoter usage and alternative splicing are operative for the differential expression of this gene.

Mutation analysis demonstrated that 5' promoter deletions and alternative promoter usage were responsible for constitutive activation of Notch1 in all T-cell lymphomas.

The PRDM1β isoform is an alternative promoter of the PRDM1 gene that may interfere with the normal role of the PRDM1a isoform.

As quantification of different Fut7 transcripts revealed a predominance of transcripts lacking the first exons in primary Th1 cells we searched for an alternative promoter.

The DRED locus itself is highly regulated by transcription from alternative promoters and alternative splicings.

Two alternative promoters underlie the transcription of two classes of HOX-5.1-specific mRNAs.

Alternative splicing (AS) and alternative promoter (AP) usage expand the repertories of mammalian transcriptome profiles and thus diversify gene functions.

We demonstrate that nearly half of all imprinted genes express both biallelic and monoallelic isoforms that are controlled by tissue-specific alternative promoters.

This study provides a global analysis of tissue-specific imprinting in humans and suggests that alternative promoters are central in the regulation of imprinted genes.

These data suggested that two alternative promoters control the renal expression of Npt2a gene and both Npt2a variant transcripts are down regulated in Hyp mice.
