**Background of RNASE10 Recombinant Protein**
RNASE10 (Ribonuclease 10) is a member of the ribonuclease A (RNASE) superfamily, a group of enzymes primarily involved in RNA metabolism. Unlike canonical RNases such as RNASE1. which exhibit ribonucleolytic activity critical for RNA degradation, RNASE10 has evolved distinct structural and functional characteristics. Phylogenetic studies suggest that RNASE10 emerged through gene duplication and divergence, particularly in primates, where it acquired specialized roles in reproduction and host defense.
Structurally, RNASE10 retains a conserved RNASE fold but lacks key catalytic residues required for enzymatic activity, rendering it a "ribonuclease-inactive" protein. This loss of enzymatic function hints at neofunctionalization. Research indicates that RNASE10 is predominantly expressed in the male reproductive tract, specifically in the epididymis, where it contributes to sperm maturation and protection. It binds to sperm surfaces, potentially modulating extracellular RNA or interacting with pathogens, suggesting dual roles in fertility and innate immunity.
The recombinant RNASE10 protein is produced using heterologous expression systems (e.g., *E. coli* or mammalian cells) to study its biological mechanisms. Purification typically involves affinity tagging (e.g., His-tag) followed by chromatography. Recombinant RNASE10 serves as a vital tool for investigating its interactions with spermatozoa, microbial membranes, or nucleic acids, aiding in elucidating its role in male fertility and reproductive health.
Interest in RNASE10 also stems from its potential clinical relevance. Aberrant expression or mutations in RNASE10 have been loosely associated with male infertility, positioning it as a biomarker or therapeutic target. Additionally, its antimicrobial properties are being explored for novel antimicrobial agents. However, challenges remain in fully characterizing its molecular partners and signaling pathways.
In summary, RNASE10 exemplifies functional diversification within the RNASE family, bridging reproductive biology and immune defense. Recombinant RNASE10 studies continue to uncover its multifaceted roles, offering insights into both basic science and translational applications.
