There are a number of ELISA Kits available for the measurement of transformation related protein 53 binding protein 1, another term for the human protein, tumor protein p53 binding protein 1. Other synonyms may include: TP53-binding protein 1, p53-binding protein 1, tumor protein 53-binding protein 1, tumor suppressor p53-binding protein 1, TDRD30, p202, and p53BP1. It is encoded by the TP53BP1 gene to yield a protein 1972 amino acids in length and 213.6 kDa in size. However, there are up to 3 reported isoforms. Versions of transformation related protein 53 binding protein 1 are present in other organisms, including: Mouse, Rat.
