Sentences with phrase «gene isoforms»

The ability of Nanopore sequencing to define the complete exonic structure of CACNA1C allows us to identify known and novel gene isoforms, including novel exons and multi-exonic skipping events and their expression across multiple brain regions.

However, its extreme length (> 13kb), number of exons (> 50) and high level of alternative splicing means CACNA1C isoform structure and expression is poorly understood, making it difficult to identify which gene isoforms confer disease risk and where they are expressed.

Since using the WormBase name of W01A8.1 (MDT - 28) would be misleading, the gene is referred here by the cosmid name W01A8.1, which gives rise to at least three protein isoforms designated W01A8.1 a, W01A8.1 b, and W01A8.1 c from at least seven different transcripts (W01A8.1 a. 1, W01A8.1 a. 2, W01A8.1 b. 1, W01A8.1 b. 2, W01A8.1 b. 3, W01A8.1 c. 1, W01A8.1 c. 2).

The heatmap shows the proportion of each isoform in the Lung samples sorted by PMI (1 indicates that only one isoform contributes to the expression of the gene and 0 that the isoform is not expressed) PMI of the samples range from 49 to 1558 minand are represented in the green to red gradient scale bar.

e APBB1IP gene has three isoforms.

This figure depicts how the expression of the longer transcript in this gene becomes less dominant as PMI increases, and, as a consequence, the abundance of the different isoforms tends to converge

As a proxy for splicing alteration, we computed the Shannon's entropy on the relative abundance of a gene's alternative splicing isoforms (Methods)-- higher values corresponding to more stochastic production of alternative isoforms.

More than half of mammalian genes generate multiple messenger RNA isoforms that differ in their 3 ′ untranslated regions (3 ′ UTRs) and therefore in regulatory sequences, often associated with cell proliferation and cancer; however, the mechanisms coordinating alternative 3 ′ - UTR processing for specific mRNA populations remain poorly defined.

A few receptor genes have more than 8 different isoforms (38 VRs and 10 ORs), however in most of these cases this is due to the presence of several transcription start sites (TSS) or exons that differ in length by just a few nucleotides, so several of the final transcripts differ only very slightly (Figure S7B).

The clearest finding from proteomics experiments is that most human genes have a single main protein isoform, while those alternative isoforms that are identified tend to be the most biologically plausible: those with the most cross-species conservation and those that do not compromise functional domains.
