Classification of Human Transcription Factors and Mouse Orthologs

Introduction

TFClass is a classification of human transcription factors (TFs) and their mouse orthologs based on the characteristics of their DNA-binding domains. It comprises four general levels (superclass, class, family, subfamily) and two levels of instantiation (genus and molecular species). Two of them (subfamily and factor species) are optional. More detailed explanations about the classification scheme and its criteria will be given here. The full classification of human TFs in its latest draft version as html document can also be obtained here, that of their mouse orthologs here, or can be downloaded as ontology in obo-format.

About this interface:
The active ontology is shown in the central part (default: human), it can be switched with the one on the right-hand side (default: mouse). To browse the classification, an individual taxon can be opened by clicking on the arrow head in front of it; clicking again closes all taxa that may have been opened. The classification of orthologs on the right-hand side opens correspondingly.

On the left-hand side, further search and browse functions as well as additional information for the highlighted taxon in the central part are provided. The search field is equipped with an autocomplete function to facilitate finding the right term among all the conceivable spelling variations. Expand / collapse all: expands the full tree in the center or collapses all parts of the tree that have been opened. Expand to: The whole classification in the center will be opened down to the selected level.

The additional information is rank- and organism-specific and changes with the selection made.

Show binding sites: Linked to (sub)family entities, if present. Clicking this option will open a selection list of all matrices that are connected with any of the TFs in this (sub)family. Chosing one of them will open the complete list of potential binding sites that (a) are located in the 1kb upstream region of human genes, (b) are conserved among human, mouse, dog and cow, and (c) have a minimum threshold as selected. Most database cross-references: Linked to TF genus entries (rank 5); links to external databases go straight to their entries. Links to UniProt isoforms and TRANSFAC proteins are also given for individual factor species.

Protein expression (human only): Displayed in a separate overlay. Based on the information provided by the Human Protein Atlas, expression sources (organs, tissues) have been linked to the Cytomer ontology.
