Transcription Factors
Transcription factors (TFs) directly interpret the genome, performing the first step in decoding the DNA sequence. Many function as ‘‘master regulators’’ and ‘‘selector genes’’, exerting control over processes that specify cell types and developmental patterning (Lee and Young, 2013) and controlling specific pathways such as immune responses (Singh et al., 2014). In the laboratory, TFs can drive cell differentiation (Fong and Tapscott, 2013) and even de-differentiation and trans-differentiation (Takahashi and Yamanaka, 2016). Mutations in TFs and TF-binding sites underlie many human diseases. Their protein sequences, regulatory regions, and physiological roles are often deeply conserved among metazoans (Bejerano et al., 2004; Carroll, 2008), suggesting that global gene regulatory ‘‘networks’’ may be similarly conserved. And yet, there is high turnover in individual regulatory sequences (Weirauch and Hughes, 2010), and over longer timescales, TFs duplicate and diverge. The same TF can regulate different genes in different cell types (e.g., ESR1 in breast and endometrial cell lines [Gertz et al., 2012]), indicating that regulatory networks are dynamic even within the same organism. Determining how TFs are assembled in different ways to recognize binding sites and control transcription is daunting yet paramount to under-standing their physiological roles, decoding specific functional properties of genomes, and mapping how highly specific expression programs are orchestrated in complex organisms.

| Description | MyoD is a transcription factor that induces transcription by binding with gene regulatory factors expressed in skeletal muscle. As a master regulatory gene, MyoD also determines skeletal muscle differentiation. References: 1) Harada et al. (2010) Hybridoma. 29:255-258. This antibody is used in ref.1. |

| Product name | Anti CCAAT/Enhancer-Binding Protein Beta (C/EBP Beta) mAb (Clone 7D2) |
| Cat No | CAC-CE-012A |
| Description | C/EBP β is a bZIP transcription factor which can bind as a homodimer to certain DNA regulatory regions. It can also form heterodimers with the related proteins CEBP-alpha, CEBP-delta, and CEBP-gamma. This protein is important in the regulation of genes involved in immune and inflammatory responses and has been shown to bind to the IL-1 response element in the IL-6 gene, as well as to regulatory regions of several acute-phase and cytokine genes.

| Cat No | CAC-CE-013A |
| Description | AATF/Che-1/Traube was identified on the basis of its interaction with MAP3K12/DLK, a protein kinase known to be involved in the induction of cell apoptosis. This protein contains an extremely acidic domain and a putative leucine zipper characteristic of transcription factors. References: 1) Ishigaki et al. (2010) Cell Death Differ. 17:774-786. |

| Cat No | CAC-CE-052A |
| Description | Oct4/Pou5f1 is a member of POU transcription factor family, which possess POU domain. This transcription factor forms a trimeric complex with SOX2 on DNA and controls the expression of a number of genes involved in embryonic development such as YES1, FGF4, UTF1 and ZFP206. Oct4/Pou5f1 is critical for early embryogenesis and for embryonic stem cell pluripotency. References: 1) Sterneckert, J. et al. (2012) Oct4 and More: The Reprogramming Expressway.

| Product name | Anti Drosophila Forkhead Box Protein O (dFOXO) pAb (Rabbit, Antiserum) |
| Cat No | CAC-THU-A-DFOXO |
| Description | Forkhead transcription factor FoxO controls various cellular processes involved in cell cycle, cell death, metabolism and oxidative stress. Recent studies have also suggested FoxO is a key molecule for lifespan regulation of various organisms. Drosophila has a single FoxO gene (dFoxO), inactivation of which is dispensable for survival. However, dFoxO appears to regulate resistance to oxidative stress and aging in Drosophila. The activity of dFoxO is regulated by phosphorylation, ubiquitination and acetylation, which may cause multiple bands of dFoxO in western blotting using this antibody. This antibody detects endogenous levels of total dFoxO protein. References: Kanao T, et al. (2010) Activation of FoxO by LRRK2 induces expression of proapoptotic proteins and alters survival of postmitotic dopaminergic neuron in Drosophila. Hum Mol Genet. 19:3747-3758. |
