Rabbit Anti-Human CAND2 polyclonal antibody for WB, IHC, ELISA. TIP120B (TATA binding protein interacting protein 120B). While bothTIP120A and TIP120B are TATA binding proteins and form complexes with various nuclear proteins involved in the control of eukaryotic gene transcription, TIP120B is expressed specifically in muscle and heart tissue. This is contrary to the ubiquitous expression of TIP120A. TIP120 homologs exist in various higher eukaryotes including D. melanogaster, C. elegans, and A. thaliana. TIP120B is 60% identical in amino acid sequence to TIP120A.
