Anti-BCAS2 antibody produced in chicken is suitable western blotting analysis at a dilution of 1:500, for tissue or cell staining at a dilution of 1:200.
Biochem/physiol Actions
Pre-mRNA-splicing factor SPF27 is a protein encoded by the BCAS2 gene in humans and is mapped to chromosome 1p13.3-21 region. It codes for a nuclear protein. BCAS2 is a novel gene up-regulated by amplification in human breast cancer cell lines. It acts as a transcriptional coactivator of estrogen receptor. It directly interacts with p53 to reduce p53 transcriptional activity and consistently decreases p53 protein in the absence of DNA damage. BCAS2 is a small nuclear protein (26kDa) and a novel negative regulator of p53. It is a potential molecular target for cancer therapy.
Physical form
Solution in phosphate buffered saline containing 0.02% sodium azide.
BCAS2 is a novel gene isolated from breast cancer cell line by differential display technique. Previously we reported that BCAS2 gene is localized on chromosome 1p13.3-21 and is up-regulated by gene amplification in breast cancer cell lines MCF-7 and BT-20.
Screening for differentially expressed genes in cancer cell lines by the RNA differential display (DD) technique identified a novel mRNA that encodes a 26-kDa protein and is up-regulated in MCF-7 and BT-20 breast cancer cells. The predicted amino acid sequence
Breast cancer amplified sequence 2 (BCAS2) was reported previously as a transcriptional coactivator of estrogen receptor. Here, we report that BCAS2 directly interacts with p53 to reduce p53 transcriptional activity by mildly but consistently decreasing p53 protein in the absence
