The JASPAR CORE database contains a curated, non-redundant set of profiles, derived from published collections of experimentally defined transcription factor binding sites for eukaryotes. An integrative cell-specific database of transcription factor binding motifs coupled with DNA methylation profiles.
The motif contains a tyrosine separated from a leucine or isoleucine by any two other amino acids, giving the signature YxxL/I. Two of these signatures are typically separated by between 6 and 8 amino acids in the cytoplasmic tail of the molecule (YxxL/Ix (6-8) YxxL/I). However, it is worth noting that in various sources, this consensus ...
CpG motifs are considered pathogen-associated molecular patterns due to their abundance in microbial genomes but their rarity in vertebrate genomes. The CpG PAMP is recognized by the pattern recognition receptor ( PRR ) Toll-Like Receptor 9 ( TLR9 ), which is constitutively expressed only in B cells and plasmacytoid dendritic cells (pDCs) in ...
A DNA sequence motif represented as a sequence logo for the LexA-binding motif. In biology, a sequence motif is a nucleotide or amino-acid sequence pattern that is widespread and usually assumed to be related to biological function of the macromolecule. For example, an N -glycosylation site motif can be defined as Asn, followed by anything but ...
Helix-turn-helix is a DNA-binding domain (DBD). The helix-turn-helix ( HTH) is a major structural motif capable of binding DNA. Each monomer incorporates two α helices, joined by a short strand of amino acids, that bind to the major groove of DNA. The HTH motif occurs in many proteins that regulate gene expression.
DNA-binding domain. A DNA-binding domain ( DBD) is an independently folded protein domain that contains at least one structural motif that recognizes double- or single-stranded DNA. A DBD can recognize a specific DNA sequence (a recognition sequence) or have a general affinity to DNA. [1] Some DNA-binding domains may also include nucleic acids ...
RNA motif. An RNA motif is a description of a group of RNAs that have a related structure. RNA motifs consist of a pattern of features within the primary sequence and secondary structure of related RNAs. Thus, it extends the concept of a sequence motif to include RNA secondary structure. The term "RNA motif" can refer both to the pattern and to ...
Arginylglycylaspartic acid ( RGD) is the most common peptide motif responsible for cell adhesion to the extracellular matrix (ECM), found in species ranging from Drosophila to humans. Cell adhesion proteins called integrins recognize and bind to this sequence, which is found within many matrix proteins, including fibronectin, fibrinogen ...
