背景信息

OCIAD2 (Ovarian Carcinoma Immunoreactive Antigen Domain-Containing Protein 2) is a transmembrane protein encoded by the OCIAD2 gene, initially identified for its potential role in ovarian cancer biology. Structurally, it contains a conserved immunoreactive antigen domain and a predicted transmembrane region, with molecular weight variations depending on post-translational modifications (typically ~25-30 kDa). Recombinant OCIAD2 protein is engineered through heterologous expression systems (e.g., E. coli, mammalian cells) to study its biochemical and functional properties in vitro.

Functionally, OCIAD2 has been implicated in mitochondrial homeostasis, apoptosis regulation, and cellular migration. It interacts with annexin A4. suggesting involvement in calcium-dependent membrane processes. Notably, OCIAD2 overexpression is observed in multiple cancers, including ovarian carcinoma, glioblastoma, and breast cancer, correlating with poor prognosis and chemoresistance. Its upregulation may promote cancer cell survival by modulating PI3K/AKT and Wnt signaling pathways. Conversely, reduced OCIAD2 expression has been linked to neurodegenerative conditions like Parkinson’s disease, highlighting tissue-specific roles.

Recombinant OCIAD2 serves as a critical tool for investigating molecular mechanisms in cancer progression and neurodegenerative disorders. Studies utilize purified protein for antibody development, binding assays, and functional studies exploring its interaction networks. Epitope-tagged versions (e.g., His-tag) facilitate protein purification and localization analysis. Emerging evidence positions OCIAD2 as a potential diagnostic biomarker and therapeutic target, particularly for cancers exhibiting its aberrant expression. However, its precise molecular mechanisms remain under active investigation, necessitating further structural and pathway analyses using recombinant protein-based approaches.
