Descriptions

RFX1 is a regulatory factor essential for MHC class II genes expression, and binds to the X boxes of MHC class II genes. This protein possesses intrinsically disordered regions (IDRs) with large negative charge, some of which involve a consecutive sequence of aspartate (D) or glutamate (E) residues, known as D/E repeats. These D/E repeats can cause autoinhibition through intramolecular electrostatic interaction with HMG boxes and modulate binding to DNA. This autoinhibited state can transition into the uninhibited complex with DNA through an electrostatically driven induced-fit process, which accelerates the target DNA search kinetics in the presence of non-functional high-affinity ligands ('decoys').

2 GO annotations of cellular component

Name Definition
extracellular region The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

3 GO annotations of molecular function

Name Definition
DNA-binding transcription factor activity, RNA polymerase II-specific A DNA-binding transcription factor activity that modulates the transcription of specific gene sets transcribed by RNA polymerase II.
RNA polymerase II cis-regulatory region sequence-specific DNA binding Binding to a specific upstream regulatory DNA sequence (transcription factor recognition sequence or binding site) located in cis relative to the transcription start site (i.e., on the same strand of DNA) of a gene transcribed by RNA polymerase II.
transcription cis-regulatory region binding Binding to a specific sequence of DNA that is part of a regulatory region that controls transcription of that section of the DNA. The transcribed region might be described as a gene, cistron, or operon.

7 GO annotations of biological process

Name Definition
cell differentiation The cellular developmental process in which a relatively unspecialized cell, e.g. embryonic or regenerative cell, acquires specialized structural and/or functional features that characterize a specific cell. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
cilium-dependent cell motility Cell motility due to the motion of one or more eukaryotic cilia. A eukaryotic cilium is a specialized organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.
DNA-templated transcription The synthesis of an RNA transcript from a DNA template.
endocrine pancreas development The process whose specific outcome is the progression of the endocrine pancreas over time, from its formation to the mature structure. The endocrine pancreas is made up of islet cells that produce insulin, glucagon and somatostatin.
epithelial cilium movement involved in determination of left/right asymmetry The movement of cilia of epithelial cells of the Left Right Organizer (LRO), also referred to as the node in mouse or the Kupffer's vesicle in zebrafish, resulting in the leftward fluid flow across the LRO and generation or transport of a signal which determines asymmetry in an organism's body plan with respect to the left and right halves.
regulation of DNA-templated transcription Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
regulation of insulin secretion Any process that modulates the frequency, rate or extent of the regulated release of insulin.
