TATA-box binding protein like 2 is a protein that in humans is encoded by the TBPL2 gene.[5] The TBPL2 protein is also known as TBP-related factor 3 (TRF3) and TATA binding protein 2 (TBP2). The protein was independently discovered in three laboratories as a vertebrate-specific family member of TATA-binding protein (TBP). [6][7][8] Orthologs have been identified in mouse, frog (Xenopus tropicalis) and fish (Danio rerio). Whereas the TBP gene is found in all eukaryotes, TBPL2 is only found in vertebrates.[9][10]

Similar to TBP, TBPL2 can bind to the TATA box. It interacts with other general transcription factors such as TFIIA and TFIIB and promotes transcription initiation in vitro.[7][8] The core domain, which mediates this binding to DNA, shows 95% identity between TBP and TBPL2.[10] The N-terminal domain of TBPL2 exhibits only limited homology to that of TBP.
