**Background of BCAS3 Recombinant Protein**
BCAS3 (Breast Carcinoma Amplified Sequence 3) is a protein-coding gene initially identified as a region amplified in breast cancer. Located on chromosome 17q23. BCAS3 has garnered attention due to its potential role in tumorigenesis, particularly in breast and ovarian cancers. The gene encodes a large multidomain protein characterized by coiled-coil motifs, which are critical for protein-protein interactions. BCAS3 is implicated in diverse cellular processes, including cell proliferation, migration, and angiogenesis, though its precise molecular mechanisms remain under investigation.
Recombinant BCAS3 protein is engineered for research applications to study its structure, function, and interactions. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells*), the recombinant protein retains key functional domains, enabling in vitro assays such as binding studies, enzymatic activity analysis, and pathway modulation experiments. Its purification often involves affinity tags (e.g., His-tag) for high yield and purity.
BCAS3 is reported to interact with components of the Wnt/β-catenin and estrogen receptor (ER) signaling pathways, suggesting a role in hormone-responsive cancers. Additionally, studies link BCAS3 to cytoskeletal regulation through associations with actin-binding proteins, influencing cell motility and metastasis. Its overexpression in tumors correlates with poor prognosis, highlighting its therapeutic potential as a biomarker or target.
Recent work also explores BCAS3's non-oncogenic functions, such as vascular development, where it regulates endothelial cell behavior. Despite progress, gaps persist in understanding its full interactome and context-dependent roles. Recombinant BCAS3 remains a vital tool for unraveling these complexities, aiding drug discovery and mechanistic studies in cancer biology.
