**Background of BCAS2 Recombinant Protein**
BCAS2 (Breast Carcinoma Amplified Sequence 2) is a multifunctional protein implicated in pre-mRNA splicing, cell cycle regulation, and genomic stability. Initially identified as a gene amplified in breast cancer, BCAS2 is a core component of the spliceosome, the molecular machinery responsible for removing introns from precursor mRNA (pre-mRNA). It interacts with splicing factors like SF3B1 and U2AF2. facilitating spliceosome assembly and ensuring accurate splicing. Beyond splicing, BCAS2 participates in diverse cellular processes, including telomere maintenance, DNA damage repair, and transcriptional regulation, often through associations with pathways involving p53. Wnt/β-catenin, and androgen receptor signaling.
Dysregulation of BCAS2 is linked to cancer progression. Overexpression of BCAS2 is observed in breast, prostate, and liver cancers, where it promotes cell proliferation, inhibits apoptosis, and enhances metastatic potential. Its role in splicing also impacts the expression of oncogenes and tumor suppressors, making it a potential therapeutic target.
Recombinant BCAS2 protein is produced using bacterial or mammalian expression systems, often tagged with His or GST for purification. This engineered protein enables in vitro studies to dissect BCAS2's molecular interactions, structural features, and biochemical activities. Researchers utilize it to investigate splicing mechanisms, screen for inhibitors, and explore its pathological roles in cancer models. Additionally, recombinant BCAS2 aids in antibody development and diagnostic assays, contributing to both basic research and translational applications in oncology and molecular biology.
