**Background of Recombinant Human SKIV2L2 Protein**
SKIV2L2 (Superkiller Viralicidic Activity 2-Like 2), also known as SKI2. is an evolutionarily conserved RNA helicase belonging to the Ski2-like family. This protein plays a critical role in RNA metabolism, particularly in mRNA surveillance and degradation pathways. It functions as a core component of the exosome complex, a multi-subunit machinery responsible for processing, degrading, or stabilizing various RNA substrates. SKIV2L2 contains a DEXH-box helicase domain that enables ATP-dependent unwinding of RNA secondary structures, facilitating 3'→5' exonucleolytic digestion by the exosome.
Structurally, SKIV2L2 acts in concert with other exosome cofactors, such as SKIV2L (homologous to yeast Mtr3) and TTC37. to form the SKI complex. This complex is essential for cytoplasmic RNA quality control, targeting aberrant transcripts (e.g., viral RNAs or misfolded mRNAs) for degradation via the exosome. Notably, SKIV2L2 is implicated in antiviral defense by restricting RNA virus replication. Dysregulation of SKIV2L2 has been associated with autoimmune disorders, including systemic lupus erythematosus (SLE), likely due to its role in clearing immunostimulatory RNA debris.
Recombinant human SKIV2L2 is produced using expression systems (e.g., HEK293 or *E. coli*) for functional studies, structural analysis, and drug discovery. Research focuses on unraveling its helicase mechanism, interactions with RNA/exosome components, and therapeutic potential in autoimmune or viral diseases.
