**Background of CCSER2 Recombinant Protein**
CCSER2 (Coiled-Coil Serine-Rich Protein 2) is a less-characterized protein encoded by the *CCSER2* gene in humans. It belongs to the coiled-coil domain-containing protein family, known for their structural roles in mediating protein-protein interactions and cellular processes such as vesicle trafficking, cytoskeletal organization, and signal transduction. The CCSER2 protein features multiple coiled-coil motifs and serine-rich regions, suggesting potential roles in scaffolding or post-translational modifications. Its exact physiological function remains unclear, though studies link it to cell cycle regulation, mitotic progression, and cell migration.
Interest in CCSER2 has grown due to its aberrant expression in cancers, including hepatocellular carcinoma and breast cancer, where it may act as an oncogenic driver by promoting tumor cell proliferation and metastasis. Additionally, bioinformatics analyses associate *CCSER2* with neurodevelopmental disorders, though experimental validation is limited.
Recombinant CCSER2 protein is engineered for *in vitro* studies to elucidate its molecular mechanisms. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), it retains functional domains for binding assays, structural analyses, or antibody development. Researchers utilize it to explore interactions with signaling partners, map phosphorylation sites in serine-rich regions, or screen for inhibitors in cancer therapeutic contexts.
Despite progress, CCSER2's full biological significance and regulatory networks remain understudied. Current efforts focus on clarifying its role in disease pathways and validating its potential as a diagnostic marker or drug target. The recombinant protein serves as a critical tool to bridge these knowledge gaps and advance translational research.
