Preparation and Storage

Background: UTF1

UTF1 (Undifferentiated embryonic cell Transcription Factor 1) is a 47-49 kDa member of Leu-zipper family of proteins. It is expressed in the early embryonic inner cell mass and primitive ectoderm, and disappears following the formation of the primitive streak. In this regard, UTF1 has been shown to be chromatin-associated and to participate in the proper differentiation of embryonic stem cells. It also is expressed in basal keratinocytes, and hair follicle matrix cells. UTF1 acts as a transcriptional coactivator of ATF2 (Activating Transcription factor 2), a bZIP family protein that interacts with CRE in gene promoters. Mouse UTF1 is 399 amino acids (aa) in length. It contains two conserved domains (aa 52-167 and aa 269-332), the latter which is key to ATS2 activation. There is one alternative start site at Met43 that generates a 39 kDa isoform. Over aa 18-423, mouse UTF1 shares 81% and 95% aa sequence identity with human and rat UTF1, respectively.
