WebJul 3, 2024 · Gene structure, transcriptional regulation, and protein synthesis. In humans, the HMGA1 gene is located on chromosome 6p21 (NC_000006.12), and it is well conserved among species (22, 23).Cloning and characterization of this gene reveal a very complex genomic organization, which includes a 5′ untranslated region (UTR) that undergoes … WebApr 8, 2024 · For example, it remains unknown whether these candidate transcription factors can directly bind to the structural genes in the terpene synthesis pathways, whether their transcriptional regulation functions are positive or negative, and whether there are interactive transcription factors involved in the regulatory network, and so on.
