The antibody is specific to WDFY3. The 50 kDa band in WB is an isoform of WDFY3.
The ubiquitously expressed cellular upstream stimulatory factor (USF) consists of 43kDa (USF-1) and 44kDa (USF-2) polypeptides which independently exhibit site-specific DNA binding and are members of the c-Myc-related family of regulatory factors containing helix-loop-helix domains. USF also contains a leucine repeat that is required for efficient DNA binding.
