NCIt definition : Zinc finger protein 40 (2718 aa, 297 kDa) is encoded by the human HIVEP1 gene. This
protein plays a role in the regulation of viral and cellular gene expression.;
NCIt note : Zinc finger protein 40 specifically binds to the DNA sequence 5'-GGGACTTTCC-3' found
in the enhancer elements of viral promoters including SV40, CMV, and HIV-1 gene promoters.
Related sequences are found in the enhancer elements of a number of cellular promoters,
including class I MHC, interleukin-2 receptor, and interferon-beta genes. (UniProt);
