背景信息

**Background of ROPN1B Recombinant Protein**

ROPN1B (Rhophilin-associated tail protein 1B), also known as Ropporin-1B, is a member of the Ropporin protein family, primarily expressed in sperm cells and associated with reproductive biology. It plays a critical role in sperm motility and fertilization by interacting with Rhophilin-1. a protein involved in regulating cytoskeletal dynamics. Structurally, ROPN1B contains conserved domains, including an N-terminal coiled-coil region and a C-terminal RII-binding domain, facilitating its interaction with regulatory subunits of protein kinase A (PKA) and other signaling molecules.

The protein is localized to the fibrous sheath of sperm flagella, where it contributes to the structural integrity and functional coordination of the tail apparatus. Studies suggest ROPN1B is essential for sperm movement by modulating PKA-mediated signaling pathways, which regulate phosphorylation events critical for flagellar bending and hyperactivation. Dysregulation of ROPN1B has been linked to male infertility, highlighting its clinical relevance.

Recombinant ROPN1B is produced using expression systems like *E. coli* or mammalian cells, enabling in vitro studies of its biochemical properties, interaction networks, and role in spermatogenesis. Its recombinant form is widely utilized in fertility research, drug screening, and diagnostic assay development to explore molecular mechanisms underlying sperm dysfunction. Additionally, ROPN1B serves as a biomarker candidate for assessing male reproductive health. Recent advances in structural biology and gene-editing tools, such as CRISPR, have further expanded its applications in studying fertilization-related disorders and potential therapeutic interventions.
