Here’s a concise description of recombinant human SSX9 protein:
Recombinant human SSX9 protein is an engineered version of the SSX family member 9 (Synovial Sarcoma X breakpoint), a cancer-testis antigen primarily expressed in germline cells and aberrantly reactivated in various malignancies. The SSX gene family (SSX1-9) encodes proteins containing a conserved SSX repression domain and a divergent C-terminal transcriptional activation domain, suggesting roles in chromatin remodeling and transcriptional regulation. SSX9 specifically interacts with polycomb-group proteins and shows nuclear localization, potentially influencing epigenetic modulation of gene expression.
As a recombinant protein, SSX9 is typically produced using bacterial or mammalian expression systems, often fused with affinity tags (e.g., His-tag) for purification. Its recombinant form enables functional studies to elucidate its dual role in normal development and oncogenesis. Current research focuses on its immunogenic properties in cancer, given the SSX family's restricted expression in normal tissues and frequent overexpression in tumors like melanoma, breast, and lung cancers. Recombinant SSX9 serves as a critical tool for developing cancer vaccines, generating specific antibodies, and studying its molecular interactions in both physiological and pathological contexts. Its precise biological function remains under investigation, with evidence suggesting involvement in cell proliferation and apoptosis regulation.
