Notes
The amino acid at position 132 is originally a "U", which has already been mutated to be "S" in the above sequence. This is due to the "U", or selenocysteine, which is encoded by UGA, is normally used as a stop codon in prokaryotic cells. Thus leading to early termination of translation. So we have substituted this "U" to simply be an "S" so that translation can proceed. Changing to cysteine may result in undesired disulfide bond formation, so serine is chosen since it is structurally related to both selenocysteine and cysteine.
Preparation and Storage
Store at -20 degrees C. For long-term storage, store at -20 degrees C or -80 degrees C. Store working aliquots at 4 degrees C for up to one week. Repeated freezing and thawing is not recommended.

NCBI Description

The protein encoded by this intronless gene belongs to the iodothyronine deiodinase family. It catalyzes the inactivation of thyroid hormone by inner ring deiodination of the prohormone thyroxine (T4) and the bioactive hormone 3,3',5-triiodothyronine (T3) to inactive metabolites, 3,3',5'-triiodothyronine (RT3) and 3,3'-diiodothyronine (T2), respectively. As in other verterbrates, studies in xenopus show that this enzyme is involved in early embryonic development. This protein is a selenoprotein, containing the rare selenocysteine (Sec) amino acid at its active site. Sec is encoded by the UGA codon, which 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. A homeolog of this gene is found on chromosome 8S. [provided by RefSeq, Jul 2017]

Uniprot Description

Responsible for the deiodination of T4 (3,5,3',5'-tetraiodothyronine) into RT3 (3,3',5'-triiodothyronine) and of T3 into T2 (3,3'-diiodothyronine). May play a protective role in selected tissues by preventing their exposure to inappropriately timed or excessive levels of thyroid hormone.

It is sometimes possible for the material contained within the vial of "Type III iodothyronine deiodinase (dio3), Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
