Product Specific Information

This peptide corresponds to 14 amino acids near the carboxy terminus of human UNG1.
PEP-0379 can be used as a blocking peptide with polyclonal antibody PA5-20264.

Target Information

The human UNG gene encodes both nuclear (UNG2) and mitochondrial (UNG1) forms of uracil-DNA glycosylase. These forms are generated by alternative splicing and the use of two differentially regulated promoters, PA and PB. The cDNAs for UNG1 and UNG2 are of similar size (2061 and 2058 bp, respectively), and thus the corresponding mRNAs are not resolved as two species in gel electrophoresis.

Nuclear UNG2 differs from mitochondrial UNG1 in 44 amino acids of the N-terminal sequence that is not necessary for catalytic activity. A major role of the UNG gene products is to repair mutagenic U:G mispairs caused by cytosine deamination. For example, UNG2 removes misincorporated dUMP residues.

The level and expression pattern of UNG1 and UNG2 differ between cell and tissue types. Additionally, the expression of UNG is cell cycle regulated and generally higher in proliferating tissues and cells compared to nonproliferating ones. UNG1 is a 304 amino acid protein, and UNG2 is a 313 amino acid protein.
