Summary
Transposable elements (TEs) are integrated into human protein-coding genes, often forming new exons from introns. This genetic integration impacts gene function and may drive species divergence.
Area of Science:
- Genomics
- Evolutionary Biology
- Molecular Biology
Background:
- Transposable elements (TEs) are mobile genetic sequences.
- Their role in shaping the genome and driving evolution is an active area of research.
Purpose of the Study:
- To investigate the genome-wide impact of transposable elements (TEs) on the evolution of protein-coding regions.
- To determine the frequency and mechanisms of TE integration into human genes.
Main Methods:
- Analysis of 13,799 human genes.
- Identification and characterization of transposable elements within protein-coding regions.
Main Results:
- Found 533 instances (4%) of TEs within protein-coding regions of human genes.
- The majority of TEs (89.5%) were integrated into introns and subsequently recruited as novel exons.
- TE integration frequently affects gene function, with examples of mouse genes largely composed of TEs, suggesting novel gene creation.
Conclusions:
- Transposable elements play a significant role in gene evolution.
- TE integration into coding regions can lead to new gene functions and potentially accelerate species divergence due to their taxon-specific nature.

02:13Overview of Transposition and Recombination
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...
02:57DNA-only Transposons
DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
The donor site from where the transposon is excised is either degraded or...

02:33Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
03:08LTR Retrotransposons
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.

03:18Non-LTR Retrotransposons
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
01:24Transposons
Transposons, or "jumping genes," are small mobile genetic elements (MGEs) that range from 700 to 40,000 base pairs in length. They are found in all organisms and can move within the same chromosome or transfer to different chromosomes. In some cases, transposons can also jump between different host DNA molecules, such as plasmids or viruses, contributing to genetic variability.Barbara McClintock first discovered these mobile genetic elements in the 1940s while studying maize genetics, and she...
