Pseudogene - Wikipedia
WEBPseudogenes are usually identified when genome sequence analysis finds gene-like sequences that lack regulatory sequences needed for transcription or translation, or whose coding sequences are obviously defective due to frameshifts or premature stop codons. Pseudogenes are a type of junk DNA .
Pseudogene - National Human Genome Research Institute
WEBApr 25, 2024 · Definition. A pseudogene is a segment of DNA that structurally resembles a gene but is not capable of coding for a protein. Pseudogenes are most often derived from genes that have lost their protein-coding ability due to accumulated mutations that have occurred over the course of evolution.

WEBJan 1, 2020 · Pseudogene RNA exists in various forms and plays a vital role in target gene expression. A pseudogene can be transcribed into antisense RNA that (A) interacts with or (B) recruits multiple negative epigenetic regulators, such as G9A, DNMT3A, and EZH2, to the promoter region of the parental gene to induce an inhibitory effect on its transcription.
