DAI Protein Kinase
DAI Protein Kinase A dsRNA-activated cAMP-independent protein serine/threonine kinase that is induced by interferon. In the presence of dsRNA and ATP, eiF-2 kinase autophosphorylates on several serine and threonine residues. The phosphorylated enzyme catalyzes the phosphorylation of the alpha subunit of eIF-2, leading to the inhibition of protein synthesis. EC 2.7.10.-
RELATED TERMS--------------------------------------
Protein
Any of a group of complex organic compounds which contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur, the characteristic element being nitrogen. Proteins, the principal constituents of the protoplasm of all cells, are of high molecular weight and consist essentially of combinations of a-amino acids in peptide linkages. Twenty different amino acids are commonly found in proteins, and each protein has a unique genetically defined amino acid sequence which determines its specific shape and function. Their roles include enzymatic catalysis, transport and storage, coordinated motion, nerve impulse generation and many others.
Interferon
A group of proteins having antiviral activity and capable of enhancing and modifying the immune response.
ATP
Adenosine triphosphate.
EiF-2
Eukaryotic initiation factor of protein synthesis. The factor consists of three subunits, alpha, beta, and gamma. As initiation proceeds, eIF-2 forms a ternary complex with Met-tRNAi and GTP.
Enzyme
A cellular protein whose shape allows it to hold together several other molecules in close proximity to each other. In this way, enzymes are able to induce chemical reactions in other substances with little expenditure of energy and without being changed themselves. Basically, an enzyme acts as a catalyst.
EIF-2
Eukaryotic initiation factor of protein synthesis. The factor consists of three subunits, alpha, beta, and gamma. As initiation proceeds, eIF-2 forms a ternary complex with Met-tRNAi and GTP.
SIMILAR TERMS--------------------------------------
DAI (Diffuse Axonal Injury)
A relatively common sequela of blunt head injury, characterized by a global disruption of axons throughout the brain. Associated clinical features may include NEUROBEHAVIORAL MANIFESTATIONS; PERSISTENT VEGETATIVE STATE; DEMENTIA; and other disorders.
PREVIOUS AND NEXT TERMS--------------------------------------
Deafness, Partial
A condition in which the sense of hearing, although defective, is functional with or without a hearing aid. The hearing loss may affect one or both ears. The normal hearing level for speech is approximately 40-70 decibels I.S.O. (International Organization for Standardization) or 30-60 db A.S.A. (American Standards Association).
Deafness, Bilateral
A general term for the complete or partial loss of the ability to hear from one or both ears. Deafness may result from EAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; or BRAIN DISEASES.
Deafness, Acquired
A general term for the complete or partial loss of the ability to hear from one or both ears. Deafness may result from EAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; or BRAIN DISEASES.
Data Processing, Computer
Data processing largely performed by automatic means.
Data Storage and Retrieval
A branch of computer or library science relating to the storage, locating, searching, and selecting, upon demand, relevant data on a given subject.
DAI Protein Kinase
Deaminase, Deoxycytidine Monophosphate
An enzyme that catalyzes the hydrolytic deamination of deoxycytidylic acid to deoxyuridylic acid and ammonia. It plays an important role in the regulation of the pool of deoxynucleotides in higher organisms. The enzyme also acts on some 5-substituted deoxycytidylic acids. EC 3.5.4.12.
Deaminase, DCMP
An enzyme that catalyzes the hydrolytic deamination of deoxycytidylic acid to deoxyuridylic acid and ammonia. It plays an important role in the regulation of the pool of deoxynucleotides in higher organisms. The enzyme also acts on some 5-substituted deoxycytidylic acids. EC 3.5.4.12.
Deaminase, Cytidine
An enzyme that catalyzes the deamination of cytidine, forming uridine. EC 3.5.4.5.

A hydrolase enzyme that converts L-asparagine and water to L-aspartate and NH3. EC 3.5.1.1.
Deaminase, AMP
An enzyme that catalyzes the deamination of AMP to IMP. EC 3.5.4.6.
