for Recombinant NSD1-SET proteinBackground

NSD1 (Nuclear Receptor Binding SET Domain Protein 1) is a histone methyltransferase that preferentially methylates lysine 36 of histone H3 and lysine 20 of histone H4 in vitro. NSD1 is a transcriptional intermediary factor capable of both negatively or positively influencing transcription, depending on the cellular context. NSD1 protein contains a SET domain, 2 LXXLL motifs, 3 nuclear translocation signals (NLSs), 4 plant homeodomain (PHD) finger regions, and a proline-rich region. The encoded protein enhances androgen receptor (AR) transactivation, and this enhancement can be increased further in the presence of other androgen receptor-associated coregulators. This protein may act as a nucleus-localized, basic transcriptional factor as well as a bifunctional transcriptional regulator. Mutations of this gene have been associated with Sotos syndrome and Weaver syndrome. One version of childhood acute myeloid leukemia is the result of a cryptic translocation with the breakpoints occurring within nuclear receptor-binding Su(var), Enhancer of zeste (EZH2), and Trithorax Domain Protein 1 on chromosome 5 and Nucleoporin, 98 kd on chromosome 11.
NSD1-SET includes the SET domain of NSD1. The SET domain is a 130 to 140 amino acid, evolutionary conserved motif that was initially characterized in the Drosophila proteins Su(var)3-9, EZH2 and TrxG and plays a crucial role in substrate recognition and enzymatic activity.
