Pattern Recognition, Visual definition: Mental process to visually perceive a critical number of facts (the pattern), such as characters, shapes, displays, or designs.
Signal Recognition Particle definition: A cytosolic ribonucleoprotein complex that acts to induce elongation arrest of nascent presecretory and membrane proteins until the ribosome becomes associated with the rough endoplasmic reticulum. It consists of a 7S RNA and at least six polypeptide subunits (relative molecular masses 9, 14, 19, 54, 68, and 72K).
NK-Tumor Recognition Protein definition: The cell surface NKTR Protein is involved in the recognition of tumor cells by large granular lymphocytes, a subpopulation of white blood cells that kill tumor cells by an MHC-independent mechanism. The protein contains a unique amino acid structure and an external cyclophilin-related domain. (from OMIM 161565 and NCI)
Prosopagnosia definition: The inability to recognize a familiar face or to learn to recognize new faces. This visual agnosia is most often associated with lesions involving the junctional regions between the temporal and occipital lobes. The majority of cases are associated with bilateral lesions, however unilateral damage to the right occipito-temporal cortex has also been associated with this condition. (From Cortex 1995 Jun;31(2):317-29)
Origin Recognition Complex definition: The origin recognition complex is a multi-subunit DNA-binding protein that initiates DNA REPLICATION in eukaryotes.
Recognition (Psychology) definition: The knowledge or perception that someone or something present has been previously encountered.
speech recognition definition: recognition and mental interpretation of spoken words; may also be used to index concept of artificial intelligence recognizing voice, ie, voice recognition programs.
cell recognition definition: The process by which a cell in a multicellular organism interprets its surroundings. [GOC:go_curators]
NKTR Gene definition: This gene is involved in the facilitation of natural killer cell interactions with target pathogens.
pattern recognition receptor activity definition: Combining with a molecular pattern based on a repeating or polymeric structure, such as a polysaccharide or peptidoglycan, to initiate a change in cell activity. Such molecular patterns are sometimes associated with potential pathogens. [PMID:12507420, PMID:12925128, PMID:14523544]
axon choice point recognition definition: The recognition of molecules at a choice point by an axon growth cone; at a choice point the growth cone determines the direction of its future growth. [PMID:10218152]
neuron recognition definition: The process by which a neuronal cell in a multicellular organism interprets its surroundings. [GOC:go_curators]
recognition of pollen definition: The process, involving the sharing and interaction of the single locus incompatibility haplotypes, involved in the recognition or rejection of the self pollen by cells in the stigma. This process ensures out-breeding in certain plant species. [GOC:dph, GOC:pj, GOC:tb]
axon target recognition definition: The process by which an axon recognizes and binds to a set of cells with which it may form stable connections. [ISBN:0878932437]
origin recognition complex definition: A multisubunit complex that is located at the replication origins of a chromosome. [GOC:elh]
cell-cell recognition definition: Cell recognition between cells, usually involving the formation of specialized cell junctions. [ISBN:0824072820]
cell-matrix recognition definition: Cell recognition that involves the interaction of the cell with the extracellular matrix. [ISBN:0824072820]
ORC1L Gene definition: This gene plays a role in DNA binding, initiation of DNA replication and transcriptional silencing. It is also involved in ATP hydrolysis and the maintenance of cell viability.
Origin Recognition Complex Subunit 1 definition: Expressed by G1 cyclin-dependent kinase activated human ORC1L Gene (ORC1 Family), 861-aa 97-kDa nuclear Origin Recognition Complex Subunit 1 is the largest of 6 conserved subunits of the ORC complex that binds to the consensus ACS of Origins in an ATP-dependent manner, serves as a platform for assembly of additional initiation factors such as CDC6 and MCM proteins, initiates DNA replication, and is essential for viability. Bound to origins throughout the cell cycle, ORC and associated factors modulate local chromatin structure to facilitate replication initiation. Selectively phosphorylated during mitosis and unlike other ORC subunits, ORC1L levels vary during the cell cycle, regulated by ubiquitin-mediated proteolysis after replication initiation. Also involved in transcriptional silencing, ORC1L may interact with MYST histone acetyltransferase 2. (NCI)
CNTNAP2 Gene definition: This gene may be involved in axonal structure.
Contactin Associated Protein-Like 2 definition: Contactin associated protein-like 2 (1331 aa, ~148 kDa) is encoded by the human CNTNAP2 gene. This protein may be involved in the structural organization of axons.
Pattern Recognition, Automated definition: In INFORMATION RETRIEVAL, machine-sensing or identification of visible patterns (shapes, forms, and configurations). (Harrod's Librarians' Glossary, 7th ed)
Pattern Recognition, Physiological definition: The analysis of a critical number of sensory stimuli or facts (the pattern) by physiological processes such as vision (PATTERN RECOGNITION, VISUAL), touch, or hearing.
Pattern Recognition definition: A branch of artificial intelligence concerned with the identification of visual or audio patterns by computers.For the computer to recognize the patterns, the patterns must be converted into digital signals and compared with patterns already stored in memory.Some uses of this technology are in character recognition, voice recognition, handwriting recognition, and robotics. (High-Tech Dictionary)
ITAM definition: ITAM (Immunoreceptor Tyrosine-based Activation Motif) or ARAM (Ag Recognition Activation Motif) (Y-X-X-L-(X)6-8-Y-X-X-L), a protein domain involved in STP, binds to SH2 domain, e.g. in CD247/x chain, FceRI g chain, or DAP12. Phosphorylated immunoreceptor signaling motifs (ITAMs) exhibit unique abilities to bind and activate Lyn and Syk tyrosine kinases. Motif may be dually phosphorylated on tyrosine that links antigen receptors to downstream signaling machinery.
phagocytosis, recognition definition: The initial step in phagocytosis involving adhesion to bacteria, immune complexes and other particulate matter, or an apoptotic cell and based on recognition of factors such as bacterial cell wall components, opsonins like complement and antibody or protein receptors and lipids like phosphatidyl serine, and leading to intracellular signaling in the phagocytosing cell. [GOC:curators, ISBN:0781735149 "Fundamental Immunology"]
Receptors, Pattern Recognition definition: A large family of cell surface receptors that bind conserved molecular structures present in pathogens. They play important roles in host defense by mediating cellular responses to pathogens.
recognition of symbiont definition: The set of specific processes that allow an organism to detect the presence of its symbiont via physical or chemical signals. The symbiont is defined as the smaller of the organisms involved in a symbiotic interaction. [GOC:cc]
recognition of host definition: The set of specific processes that allow an organism to detect the presence of its host via physical or chemical signals. The host is defined as the larger of the organisms involved in a symbiotic interaction. [GOC:cc]
recognition of apoptotic cell definition: The process by which a cell interprets signals (in the form of specific proteins and lipids) on the surface of a dying cell which it will engulf and remove by phagocytosis. [GOC:rk, PMID:15536015]
Methylation Site definition: A sequence in DNA that can be recognized by a specific methylase enzyme and that contains the specific base target for methyl transfer.
Automated Facial Recognition definition: Electronic identification of a human based on attributes of the face.
recognition definition: Reconnaissance.
