Transcription factors (TFs) are a special class of DNA-binding proteins that orchestrate gene transcription by recruiting other TFs, co-activators or co-repressors. Their combinatorial interplay in higher organisms maintains homeostasis and governs cell identity by finely controlling and regulating tissue-specific gene expression. Despite the rich literature on the importance of cooperative TFs for deciphering the mechanisms of individual regulatory programs that control tissue specificity in several organisms such as human, mouse, or Drosophila melanogaster, to date, there is still need for a comprehensive study to detect specific TF cooperations in regulatory processes of cattle tissues. To address the needs of knowledge about specific combinatorial gene regulation in cattle tissues, we made use of three publicly available RNA-seq datasets and obtained tissue-specific gene (TSG) sets for ten tissues (heart, lung, liver, kidney, duodenum, muscle tissue, adipose tissue, colon, spleen and testis). By analyzing these TSG-sets, tissue-specific TF cooperations of each tissue have been identified. The results reveal that similar to the combinatorial regulatory events of model organisms, TFs change their partners depending on their biological functions in different tissues. Particularly with regard to preferential partner choice of the transcription factors STAT3 and NR2C2, this phenomenon has been highlighted with their five different specific cooperation partners in multiple tissues. The information about cooperative TFs could be promising: i) to understand the molecular mechanisms of regulating processes; and ii) to extend the existing knowledge on the importance of single TFs in cattle tissues.

An RNA POLYMERASE II specific transcription factor. It may play a role in transcriptional activation of gene expression by interacting with the TATA-BOX BINDING PROTEIN component of TRANSCRIPTION FACTOR TFIID.
A tissue-specific subunit of NF-E2 transcription factor that interacts with small MAF PROTEINS to regulate gene expression. P45 NF-E2 protein is expressed primarily in MEGAKARYOCYTES; ERYTHROID CELLS; and MAST CELLS.
A basic-leucine zipper transcription factor that regulates GLOBIN gene expression and is related to TRANSCRIPTION FACTOR AP-1. NF-E2 consists of a small MAF protein subunit and a tissue-restricted 45 kDa subunit.
Maf transcription factors are a family of basic-leucine zipper transcription factors that are closely related to V-MAF ONCOGENE PROTEIN. The C-MAF PROTO-ONCOGENE PROTEIN was the first mammalian Maf transcription factor identified, and now the family is known to include a variety of other Maf proteins such as MAFB TRANSCRIPTION FACTOR; MAFF TRANSCRIPTION FACTOR; MAFG TRANSCRIPTION FACTOR; and MAFK TRANSCRIPTION FACTOR.
An RNA POLYMERASE II specific transcription factor. It plays a role in assembly of the pol II transcriptional preinitiation complex and has been implicated as a target of gene-specific transcriptional activators.
