Gene: DIO2

Official Full Name: iodothyronine deiodinase 2provided by HGNC

Gene Summary: The protein encoded by this gene belongs to the iodothyronine deiodinase family. It catalyzes the conversion of prohormone thyroxine (3,5,3',5'-tetraiodothyronine, T4) to the bioactive thyroid hormone (3,5,3'-triiodothyronine, T3) by outer ring 5'-deiodination. This gene is widely expressed, including in thyroid and brain. It is thought to be responsible for the 'local' production of T3, and thus important in influencing thyroid hormone action in these tissues. It has also been reported to be highly expressed in thyroids of patients with Graves disease, and in follicular adenomas. The intrathyroidal T4 to T3 conversion by this enzyme may contribute significantly to the relative increase in thyroidal T3 production in these patients. This protein is a selenoprotein containing the non-standard amino acid, selenocysteine (Sec), which is encoded by the UGA codon that normally signals translation termination. The 3' UTRs of selenoprotein mRNAs contain a conserved stem-loop structure, designated the Sec insertion sequence (SECIS) element, that is necessary for the recognition of UGA as a Sec codon, rather than as a stop signal. Unlike the other two members (DIO1 and DIO3) of this enzyme family, the mRNA for this gene contains an additional in-frame UGA codon that has been reported (in human) to function either as a Sec or a stop codon, which can result in two isoforms with one or two Sec residues; however, only the upstream Sec (conserved with the single Sec residue found at the active site in DIO1 and DIO3) was shown to be essential for enzyme activity (PMID:10403186). Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Oct 2018]

Background

DIO2 Gene Knockout Cell Lines are specialized in vitro cellular models engineered to lack the functional Dio2 gene, which encodes for the deiodinase enzyme responsible for converting the prohormone thyroxine (T4) into the active form triiodothyronine (T3). This gene knockout provides an invaluable tool for researchers studying thyroid hormone signaling pathways, metabolic processes, and related endocrine disorders. The absence of DIO2 allows for direct investigation into the physiological impacts of altered thyroid hormone activity, enabling deeper insights into conditions such as hypothyroidism and metabolic syndrome.

The primary function of these cell lines lies in their ability to facilitate the study of cellular responses to varying thyroid hormone levels without the confounding effects of DIO2 activity. By using these knockout models, researchers can precisely analyze gene expression, receptor interactions, and down-stream signaling cascades in response to T4 and T3 treatment. Additionally, these cell lines can be utilized to evaluate potential therapeutic interventions targeting thyroid hormone-related pathways, thereby enhancing the relevance of preclinical findings for clinical applications.

The scientific importance of DIO2 Gene Knockout Cell Lines extends beyond basic research; they have significant implications in drug development and endocrine system studies. They serve as a model for understanding the pharmacodynamics of thyroid hormone analogs and can assist in distinguishing whether observed effects are due to direct thyroid hormone action or other metabolic changes.

What sets our DIO2 Gene Knockout Cell Lines apart from alternative models is the precision of gene editing techniques employed, ensuring high specificity and reliability of the knockout. Unlike transient knockdown methods, our stable knockout lines remain consistent across experiments, thus providing reproducible data for long-term studies. Furthermore, we maintain rigorous quality control and validation processes, ensuring the integrity and functionality of our cell lines.

For researchers and clinicians seeking insights into thyroid hormone action and its implications in health and disease, these cell lines represent a cornerstone model that can lead to novel therapeutic strategies and enhanced understanding of metabolic regulation. Our company specializes in providing high-quality biological products, backed by a team of experts who are dedicated to supporting research advancements through innovative solutions tailored to the scientific community's needs.
