General description

Undifferentiated embryonic cell transcription factor 1 is a nucleus protein encoded by the UTF1 gene in human and functions as a transcriptional coactivator of ATF2. UTF1 is reported to interact with the ATF-2 metal binding motif via the leucine zipper motif within its conserved domain 2 (CD2) and both CD1 & CD2 of UTF1 and also independently mediates association with TATA-binding protein-containing complex. (PMID 9749258)


Other homologies: mouse, rat 95%.


Epitope: Near N-terminus

KLH-conjugated linear peptide corresponding to human UTF1 near N-terminus.


Anti-UTF1 Antibody is an antibody against UTF1 for use in Western Blotting and Immunohistochemistry.

Immunohistochemistry Analysis: A 1:50 dilution from a representative lot detected UTF1 in mouse kidney and rat liver tissue.
