Descriptions

NFκB1 is a nuclear factor NFκB p105 subunit (p50 and its precursor p105), and plays pivotal role in the regulation of the inflammatory response to pathogens, autoimmune diseases, and cancerous cells. The five members of the NF-κB family are normally kept inactive in the cytoplasm by interaction with inhibitors called IκBs or the unprocessed forms of NF-κB1 and NF-κB2. The C-terminal ankyrin repeats of p105 allow it to serve as an IkappaB-like function. The ankyrin repeats interact with and shield the nuclear localization signal located at the end of Rel-homology domain (RHD) domain and DNA binding of Rel/NF-kappaB complexes. RHD domain mediates DNA binding.

12 GO annotations of cellular component

Name Definition
cell junction A cellular component that forms a specialized region of connection between two or more cells, or between a cell and the extracellular matrix, or between two membrane-bound components of a cell, such as flagella.
cell projection A prolongation or process extending from a cell, e.g. a flagellum or axon.
cortical actin cytoskeleton The portion of the actin cytoskeleton, comprising filamentous actin and associated proteins, that lies just beneath the plasma membrane.
filopodium Thin, stiff, actin-based protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal or dendritic growth cone, or a dendritic shaft.
focal adhesion A cell-substrate junction that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments. In insects focal adhesion has also been referred to as hemi-adherens junction (HAJ).
glutamatergic synapse A synapse that uses glutamate as a neurotransmitter.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
postsynaptic density membrane The membrane component of the postsynaptic density. This is the region of the postsynaptic membrane in which the population of neurotransmitter receptors involved in synaptic transmission are concentrated.
postsynaptic density, intracellular component A network of proteins adjacent to the postsynaptic membrane forming an electron dense disc. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize neurotransmitter receptors in the adjacent membrane, such as anchoring and scaffolding molecules, signaling enzymes and cytoskeletal components.
sarcomere The repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.
striated muscle thin filament Filaments formed of actin and associated proteins; attached to Z discs at either end of sarcomeres in myofibrils.
Z disc Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached.

13 GO annotations of molecular function

Name Definition
actin filament binding Binding to an actin filament, also known as F-actin, a helical filamentous polymer of globular G-actin subunits.
calcium ion binding Binding to a calcium ion (Ca2+).
cytoskeletal protein binding Binding to a protein component of a cytoskeleton (actin, microtubule, or intermediate filament cytoskeleton).
FATZ binding Binding to a member of the FATZ family of proteins, filamin-, actinin-, and telethonin-binding proteins of the Z-disc of striated muscle. FATZ proteins are located in the Z-disc of the sarcomere and are involved in a complex network of interactions with other Z-band components.
identical protein binding Binding to an identical protein or proteins.
LIM domain binding Binding to a LIM domain (for Lin-11 Isl-1 Mec-3) of a protein, a domain with seven conserved cysteine residues and a histidine, that binds two zinc ions and acts as an interface for protein-protein interactions.
nuclear receptor coactivator activity A transcription coactivator activity that activates or increases the transcription of specific gene sets via binding to a DNA-bound nuclear receptor, either on its own or as part of a complex. Coactivators often act by altering chromatin structure and modifications. For example, one class of transcription coregulators modifies chromatin structure through covalent modification of histones. A second class remodels the conformation of chromatin in an ATP-dependent fashion. A third class modulates interactions of DNA-bound DNA-binding transcription factors with other transcription coregulators. A fourth class of coactivator activity is the bridging of a DNA-binding transcription factor to the general (basal) transcription machinery. The Mediator complex, which bridges sequence-specific DNA binding transcription factors and RNA polymerase, is also a transcription coactivator.
phosphatidylinositol-4,5-bisphosphate binding Binding to phosphatidylinositol-4,5-bisphosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 4' and 5' positions.
protein domain specific binding Binding to a specific domain of a protein.
protein-macromolecule adaptor activity The binding activity of a protein that brings together two or more macromolecules in contact, permitting those molecules to function in a coordinated way. The adaptor can bring together two proteins, or a protein and another macromolecule such as a lipid or a nucleic acid.
titin binding Binding to titin, any of a family of giant proteins found in striated and smooth muscle. In striated muscle, single titin molecules span half the sarcomere, with their N- and C-termini in the Z-disc and M-line, respectively.
titin Z domain binding Binding to a titin Z protein domain, which recognizes and binds to the C-terminal calmodulin-like domain of alpha-actinin-2 (Act-EF34), adopts a helical structure, and binds in a groove formed by the two planes between the helix pairs of Act-EF34.
transmembrane transporter binding Binding to a transmembrane transporter, a protein or protein complex that enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other.
