ERBP, or Deoxynucleotidyltransferase, terminal, interacting protein 2, is a human gene encoded by DNTTIP2. It may also be known as: Deoxynucleotidyltransferase terminal-interacting protein 2; Estrogen receptor-binding protein; LPTS-interacting protein 2; LPTS-RP2; Terminal deoxynucleotidyltransferase-interacting factor 2; TdIF2; TdT-interacting factor 2; acidic 82 kDa protein mRNA; FCF2; HSU15552. The encoded protein has an amino acid length of 756 and a mass of 84.5 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Chicken.
