Genomic features
9 recordsExon
A gene segment retained in a mature RNA after processing; an exon may contain coding sequence, untranslated sequence, or both.
Promoter
A DNA region near a transcription start site where RNA polymerase and associated proteins assemble to begin transcription.
3′ Untranslated region (3′ UTR) · 3′ untranslated region (3′ UTR)
The transcribed portion of an mRNA after its coding sequence that can influence RNA stability, location, and translation.
5′ Untranslated region (5′ UTR) · 5′ untranslated region (5′ UTR)
The transcribed portion of an mRNA before its coding sequence; it is present in the mature message but is not part of the main protein-coding region.
Coding Sequence (CDS) · Coding sequence (CDS)
The part of a transcript annotated as specifying a protein sequence, from its translation start through its termination codon.
Enhancer
A regulatory DNA region that can raise transcription by binding regulatory proteins and communicating with a promoter.
Intron
A transcribed region removed from many eukaryotic RNA precursors during RNA splicing.
Open Reading frame (ORF) · Open reading frame (ORF)
A sequence that can be read in one codon frame without an in-frame stop; a long ORF can suggest protein-coding potential but does not prove expression.
Transcription Start site · Transcription start site
The DNA position where RNA polymerase begins synthesizing a particular RNA transcript.
