cDNA probes for three components of the erythroid membrane skeleton, alpha spectrin, beta spectrin, and ankyrin, were obtained by using monospecific antibodies to screen a lambda gt11 expression vector library containing cDNA prepared from chicken erythroid poly(A)+ RNA. Each cDNA appears to hybridize to one gene type in the chicken genome. Qualitatively distinct RNA species in myogenic and ery...
The binding specificity of rheumatoid factors (RFs) to human Fc resembles that of some microbial Fc-binding proteins, suggesting conformational similarities in their Fc-binding regions. Using polyclonal chicken antibodies against SPA, we have detected a crossreactive determinant shared by human RFs from different individuals, but not by non-RF IgM and IgG. Chicken anti-SPA was shown to bind to ...
Two closely related protein-tyrosine kinases with the characteristics of growth factor receptors were identified by screening a chicken embryo cDNA expression library with anti-phosphotyrosine antibodies and were designated Cek2 and Cek3 (chicken embryo kinases 2 and 3). Cek2 and Cek3 are structurally related to Cek1, a chicken basic fibroblast growth factor receptor, and presumably represent r...
Acetylcholine receptors that bind nicotine with high affinity but do not bind alpha-bungarotoxin have recently been immunoaffinity purified from brains of chickens and rats (Whiting and Lindstrom, 1986a, b; Whiting and Lindstrom, 1987a). Antisera to these receptors bind to the nicotinic receptors that regulate cation channel opening on chick ciliary ganglion neurons (Stollberg et al., 1986) and...
We have constructed a genomic DNA expression library and screened it with antibodies in order to clone the deb-1 gene from the nematode Caenorhabditis elegans. This gene encodes a protein found at the base of the muscle dense-bodies, structures which attach actin thin filaments to the sarcolemma. We report the complete sequence of the deb-1 gene, its localization on the C. elegans genetic map, ...
Proteins that normally function in amyloid form are found bacteria, yeast, plants and vertebrates, including humans. In particular, fibrils amyloid-like structures described the germ cells of various organisms. Recently we showed chicken oocytes there some nuclear stained by amyloid-specific dye thioflavin S. Here demonstrate S binds giant terminal RNP aggregates lampbrush chromosomes. However,...
A cytoskeleton-associated glycoprotein of 130-kilodalton molecular mass (GP 130) was purified from a nonionic detergent-insoluble fraction of 10-16-d-old chicken embryo brains. GP 130 is tightly associated with other proteins in actin-containing complexes (Moss, D.J., 1983, Eur. J. Biochem., 135:291-297); thus, pure protein preparations were obtained only after the partial dissociation of the c...
The emergence of West Nile (WN) virus in New York and the surrounding area in 1999 prompted an increase in surveillance measures throughout the United States, including the screening of sentinel chicken flocks for antibodies. An enzyme-linked immunosorbent assay (ELISA) for the detection of chicken immunoglobulin M (IgM) to WN virus was developed, standardized, and characterized as a rapid and ...
CIAV infection in chicken flocks has been described in most countries with a developed chicken industry and can result in economically important clinical or subclinical disease in broiler chickens. In this study sera samples from 46 poultry flocks in Sharekord area, Iran, were tested for the presence of chicken infectious anemia virus (CIAV) antibodies using a commercial enzyme-linked immunosor...
In contrast to a number of studies on the humanization of non-human antibodies, the reshaping of a non-human antibody into a chicken antibody has never been attempted. Therefore, nothing is known about the animal species-dependent compatibility of the framework regions (FRs) that sustain the appropriate conformation of the complementarity-determining regions (CDRs). In this study, we attempted ...
