Example Input:  Inhibition of Raf - 1 signaling by a monoclonal antibody , which interferes with Raf - 1 activation and with Mek substrate binding .
Example Output: Raf - 1

Example Input:  Using beta 1 - AR - luciferase reporter recombinants , we have previously determined that important beta 1 - AR genetic elements controlling expression within the C6 glioma cell line are contained within the region - 396 to - 299 , relative to the translational start site .
Example Output: luciferase reporter

Example Input:  The polypeptide encoded by the cDNA contained 450 amino acids with a calculated M ( r ) of 52 , 057 , and showed significant homology with human and mouse CAD ( 22 % identity ) .
Example Output:
mouse CAD
