Western blot of neonatal rat brain lysate showing specific immunolabeling of the ~62 kDa COBRA1 protein.
Anti-COBRA1 (NELF-B) Antibody
Bulk Order Anti-COBRA1 (NELF-B) Antibody
COBRA1 (cofactor of BRCA1) also known as NELF-B, is an essential component of the negative elongation factor (NELF) complex. COBRA1 has been shown to directly bind estrogen receptor alpha (ERα) and repress ERα-mediated transcription (Aiyar SE et al., 2004). COBRA1 has also been demonstrated to interact with c-Jun and c-Fos suggesting a role in modulation of the AP-1 pathway and therefore may be important in cell proliferation, differentiation, apoptosis and oncogenesis (Zhong H et al., 2004)
