INSIG1 Divergent Transcript (INSIG1-DT)

INSIG1 Divergent Transcript (INSIG1-DT) is a long non-coding RNA gene located near the INSIG1 protein-coding gene. Divergent transcripts are a class of lncRNAs transcribed from regions close to protein-coding genes (within 300-500 bases) in the opposite (divergent) orientation, and often originate from shared promoter regions[9]. INSIG1-DT does not encode a protein, and its direct biological function is not well characterized. However, transcriptomic studies show that expression of specific non-coding transcripts, including INSIG1-DT, is associated with clinical and prognostic features in cancers such as prostate cancer, suggesting its potential utility as a transcript-specific biomarker[4][5]. There is no clear evidence that INSIG1-DT serves as a therapeutic target (e.g., receptor, enzyme, drug interactor). It should not be confused with the protein-coding gene INSIG1 (Insulin-induced gene 1 protein), which plays a major role in cholesterol metabolism and SREBP signaling[3][6]. The gene "INSIG1 Divergent Transcript" (INSIG1-DT) is a long non-coding RNA, not a protein target or receptor, and hence is not a therapeutic target in the classic sense[5][9]. Sometimes, lncRNAs are explored as biomarkers or as putative therapeutic targets for RNA-based drugs, but as of now, there is insufficient evidence to classify INSIG1-DT as such. It is not to be confused with the protein "INSIG1" or related protein-coding variants/circular RNAs derived from the INSIG1 locus[1][5].
