Sequence of SEPP1 recombinant protein

There are 10 selenocysteine (U) in the original sequence. The amino acids at multiple sites are ‘U’ in UniProt (yellow highlighted; U59S, U300S, U318S, U330S, U345S, U352S, U367S, U369S, U376S, U378S), reference:: https://www.uniprot.org/uniprot/P49908 ). The ‘U’ at each yellow highlighted site has been mutated to ‘S’ to manufacture the MBS1065524 Recombinant Human Selenoprotein P. 'U' selenocysteine is encoded by UGA and it is normally used as a stop codon in prokaryotic cells, which will lead to early termination of translation, hence the lab mutates this selenocysteine for protein manufacturing. In terms of the formation of selenocysteine, selenocysteine is actually a derivative of serine. Selenocysteine and cysteine as well as serine are all highly similar. This selenocysteine can be regarded as either the 'S' of cysteine replaced by Se, or the 'O' of serine replaced by Se. The selenocysteine can mutated to be either serine or cysteine.

Generally, the lab mutates 'U' to serine for protein expression because mutating the 'U' to cysteine may result in the formation of additional disulfide bonds, potentially affecting the expression and structure of the protein.

NCBI Summary for SEPP1

This gene encodes a selenoprotein containing multiple selenocysteine (Sec) residues, which are encoded by the UGA codon that normally signals translation termination. The 3' UTR of selenoprotein genes have a common stem-loop structure, the sec insertion sequence (SECIS), which is necessary for the recognition of UGA as a Sec codon rather than as a stop signal. This selenoprotein is an extracellular glycoprotein, and is unusual in that it contains 10 Sec residues per polypeptide. It is a heparin-binding protein that appears to be associated with endothelial cells, and has been implicated to function as an antioxidant in the extracellular space. Several transcript variants, encoding either the same or different isoform, have been found for this gene. [provided by RefSeq, Jul 2008]
