**Background of Recombinant Human SFRS17A Protein**
SFRS17A (also termed SRSF17 or SFRSG) is a member of the serine/arginine-rich (SR) protein family, crucial in pre-mRNA splicing and RNA processing. These proteins contain RNA recognition motifs (RRMs) and RS domains, enabling interactions with spliceosome components and regulatory RNA elements. SFRS17A is particularly noted for its role in gametogenesis and early development, with high expression in germ cells and certain cancers.
As a splicing regulator, SFRS17A modulates splice site selection, influencing transcript diversity and protein isoform production. Dysregulation of SFRS17A is linked to reproductive disorders and oncogenesis, likely through aberrant splicing of genes involved in cell proliferation and apoptosis. Recombinant SFRS17A protein, typically produced in *E. coli* or mammalian systems, retains post-translational modifications critical for its function. This recombinant form enables studies on its structural features, spliceosomal interactions, and phosphorylation dynamics mediated by kinases like SRPK1.
Research applications include dissecting splicing mechanisms, modeling SFRS17A-related pathologies, and screening therapeutic compounds targeting splicing anomalies. Its conserved role across species underscores its biological significance, making it a valuable tool in RNA biology and disease research.
