|---|---|---|---|
| 설명 | 1. 한쪽 눈에 빛을 비추면, 이 빛은 시각신경에 의해 뇌에 전달되고, 이 자극은 사람의 의지와 무관하게 곧, 눈돌림신경으로 전달되어 양쪽 눈의 동공이 축소하게 된다. 이런 모든 일련의 과정을 빛반사라 부르는데 이것은 사람이 어두운 곳에 가거나 어두운 곳에서 갑자기 밝은 곳에 나갔을 때, 동공이 반사적으로 움직이는 것과 같은 것이다. 2. 고막에서 반사하는 광상. 3. 망막경의 거울로 망막에서 반사하는 고리모양의 많은 점. |

| gene rearrangement, b-lymphocyte, light chain | Ordered rearrangement of b-lymphocyte variable gene regions coding for the kappa or lambda light chains, thereby contributing to antibody diversity. It occurs during the second stage of differentiation of the immature b-lymphocyte. (12 Dec 1998) |
|---|---|
| P light chain | <protein> Myosin light chain that can be phosphorylated by myosin light chain kinase, as a result of phosphorylation, the myosin is activated. (18 Nov 1997) |
| myosin light chain | <protein> The light chains of the muscle protein myosin. Each molecule of myosin is composed of two heavy chains and two pairs of light chains. The light chains have a molecular weight of about 20 kD and there is one dissimilar pair of light chains associated with each heavy chain. The proteins all have sequence homology to calmodulin, but not all with calcium binding activity. Several types are known: regulatory light chains (LC 2, DNTB light chains) probably regulate the ATPase activity of the heavy chain directly (through the binding of calcium) or indirectly (activating when they themselves are phosphorylated by myosin light chain kinase) and essential light chains (LC 1, LC 3, alkali light chains), which have a more subtle and apparently nonessential role. In molluscan muscle the EDTA light chains (similar to LC 2 from vertebrate muscle) confer calcium sensitivity on the myosin itself. The light chains are "calmodulin-like" proteins that bind calcium. Two of them can be removed easily, and two with difficulty. The light chains bind the heavy chains in the vicinity of the head groups of the myosin. (12 Dec 1998) |
| myosin light chain kinase | <enzyme> An enzyme that phosphorylates myosin light chains in the presence of ATP to yield myosin-light chain phosphate and ADP, and requires calcium and calmodulin. The 20-kD light chain is phosphorylated more rapidly than any other acceptor, but light chains from other myosins and myosin itself can act as acceptors. The enzyme plays a central role in the regulation of smooth muscle contraction. Chemical name: ATP:myosin-light-chain O-phosphotransferase Registry number: EC 2.7.1.117 (12 Dec 1998) |
| immunoglobulins, light-chain | Polypeptide chains, consisting of 211 to 217 amino acid residues, isolated from immunoglobulins and having a molecular weight of approximately 22 kD. There are two major types of light chains, kappa and lambda. In man they are found in a ratio of 60% to 40%, respectively. Both chains consist of linear repeating, similar, but not identical, segments of about 110 amino acid residues. In each segment a disulfide bond establishes a tightly folded approximately 60-membered loop or domain. Adjacent domains are linked by less tightly folded regions. Both light chains contain two such domains. Two light and two heavy chains make one immunoglobulin molecule, but both light chains in one ig are of the same type. (12 Dec 1998) |
| EDTA light chain | <protein> Myosin light chains (18 kD) from scallop muscle (two per pair of heavy chains), easily extracted by calcium chelation. Although the EDTA light chains do not bind calcium they confer calcium sensitivity on the myosin heavy chains. (18 Nov 1997) |
| light chain | <immunology, protein> The lighter of the two types of polypeptide chains that are found in immunoglobulin and antibody molecules. Also used as a non-specific term for the smaller subunits of several multimeric proteins such as immunoglobulin, myosin, dynein, clathrin. (14 Oct 1997) |
| light chain-related amyloidosis | A form of primary amyloidosis in which the fibrillar amyloid deposits are derived from the amino terminal variable region of the light chains of immunoglobulin; seen in B-lymphocyte and plasma-cells dyscrasias. (05 Mar 2000) |
| chain, orthodontic chain | <dentistry> A stretchable plastic chain used to hold archwires into brackets and to moke teeth. (08 Jan 1998) |
| amyloid beta-protein | A 4 kD protein, 39-43 amino acids long, expressed by a gene located on chromosome 21. It is the major protein subunit of the vascular and plaque amyloid filaments in individuals with alzheimer's disease and in aged individuals with trisomy 21 (down syndrome). The protein is found predominantly in the nervous system, but there have been reports of its presence in non-neural tissue. (12 Dec 1998) |
| amyloid beta-protein precursor | A precursor to the amyloid-beta protein (beta/a4). Alterations in the expression of the amyloid beta-protein precursor (abpp) gene, located on chromosome 21, plays a role in the development of the neuropathology common to both alzheimer disease and down syndrome. Abpp is associated with the extensive extracellular matrix secreted by neuronal cells. Upon cleavage, this precursor produces three proteins of varying amino acid lengths: 695, 751, and 770. The beta/a4 (695 amino acids) or beta-amyloid protein is the principal component of the extracellular amyloid in senile plaques found in alzheimer disease, down syndrome and, to a limited extent, in normal aging. (12 Dec 1998) |
| amyloid precursor protein | <protein> Individuals with Alzheimer's disease are characterised by extensive accumulation of amyloid in the brain, referred to as senile plaques. These consist of a core of amyloid fibrils surrounded by dystrophic neurites. The principal component of the amyloid fibrils is B/A4, a peptide derived from the larger APP. The specific role of amyloid protein is unclear but it is thought that amyloid deposits may cause neurons to degenerate. Amyloid deposits also occur in brains of older Down's Syndrome patients. (04 May 1997) |
| amyloid protein | Glycoprotein deposited extracellularly in tissues in amyloidosis. The glycoprotein may either derive from light chain of immunoglobulin (AIO (amyloid of immune origin): 5-18 kD glycoprotein, product of a single clone of plasma cells, the N terminal part of lambda or kappa light chain) or, in what used to be referred to as AUO, amyloid of unknown origin, from serum amyloid A (SAA), one of the acute phase proteins that increases many fold in inflammation. The polypeptides are organised as a _ pleated sheet making the material rather inert and insoluble. Minor protein components are also found. Should be distinguished from _ amyloid deposited in the brain and that is derived from amyloid precursor protein (see amyloidogenic glycoprotein. (18 Nov 1997) |
| amyloid protein aa | A nonimmunoglobulin amyloid isolated from amyloid fibrils deposited in amyloidosis secondary to chronic inflammatory diseases such as rheumatoid arthritis. Antisera to amyloid protein aa have been used to detect a related serum protein saa. (12 Dec 1998) |
| amyloid protein saa | A serum protein believed to be a circulating precursor to amyloid protein aa. It is present in low concentrations in normal sera, but found in much higher concentrations in sera of older persons and in patients with amyloidosis or with diseases known to predispose to amyloidosis. Very high levels of this protein have been reported during acute inflammatory episodes. Antisera to amyloid protein aa cross-react with protein saa. (12 Dec 1998) |
| amyloid light chain protein |
a pathological fibrillar low-molecular-weight protein occurring in immunocyte-derived amyloidosis; it is structurally and immunologically similar to the variable region of either the kappa chains or the lambda chains of immunoglobulins. Called also AL p. See also amyloid (def. 3).
