Each gene MODEL can encode several mRNA EXONS and represent the spliced, intronless portions of the gene. An mRNA EXON may only partially code for a protein; exactly the case where upstream or downstream untranslated regions exist. The protein coding portion of an individual EXON is represented ...
They are initiated from a second distal DDX3Y promoter domain at two distinct start sites in the genes 5 untranslated region (UTR) exon-T sequence. With the aid of an EGFP-3xFLAG reporter cassette cloned downstream of DDX3Y minigenes containing exons 14 and two different exon-T extensions, ...
▲snRNA has different genes in multiple copies, which play different roles in the synthesis of other RNA classes, such as, snRNA which is part of thespliceosomesthat help in the conversion of pre-messenger RNA (hnRNA) into mRNA ...
Thus, genes with long 5UIs tend to have a high total intronic length and longer 5'UTR exons. While this tendency holds in genes with additional introns, several genes with total 5UI lengths greater than 10 kb lack any coding-region or 3'UTR introns (Figure 1d). On the other hand, amo...
When investigated in a model cell system, these lengthened UTR conferred reduced transcript stability and, for one of these isoforms, short uORFs introduced by the added length altered protein expression kinetics. This study highlights instances in which current reference databases are incomplete ...

(GUS) gene reporter system in transgenicArabidopsis. The results were as follows:AhFAD2-1A/Bgenes consisted of two exons and one intron within their 5'-UTR; promoter ofAhFAD2-1Awas too weak to be detected and the promoter ofAhFAD2-1Bpoorly activated the expression level ofGUSin cotyledon ...
