|Cat. No. :
||Human Upstream Stimulatory Factor 1 (USF1) regulates the transcription of many genes involved in lipid and glucose homeostasis and co-localizes with familial combined hyperlipidemia (FCHL) and type 2-diabetes on chromosome 1q22-23. The USF1 protein can activate transcription through pyrimidine-rich initiator (Inr) elements and E-box motifs. It is a basic helix-loop-helix leucine zipper (b-HLH-ZIP) protein that shares a common DNA-binding specificity with the c-Myc oncoproteins.
||Liquid. Supplied in 20 mM Tris-HCl pH 8.0, 20% glycerol, 100 mM KCl, 0.2 mM EDTA and 1 mM DTT.
||>95% by SDS-PAGE.
||5-50 ng are sufficient for DNA binding assays, 50-500 ng are required for in vitro transcription assays and 100 ng are required for protein-protein interaction assays.
