Amyloid P protein in pseudoexfoliative fibrillopathy

Current Eye Research, 1989
Amyloid P protein was demonstrated by immunostaining in all 14 samples of ocular and conjunctival pseudoexfoliative (PSX) material studied, although amyloid was not found by Congo red staining or ultrastructurally. Immunostaining of PSX aggregates for other common amyloid proteins, including amyloid A, prealbumin, and immunoglobulin light chains, was ...

The acidic ribosomal P proteins

The International Journal of Biochemistry & Cell Biology, 2002
The acidic ribosomal P proteins (pI 3-4) are unique among ribosomal constituents: the only molecules on the ribosomes existing in multiple copies, they form a hetero-oligomeric complex (P1/P2)(2) recognizable as a lateral protuberance on the 60S ribosomal subunit, which is thought to be directly involved in interactions with elongation factors during ...

Is P-protein actin-like?-not yet

Planta, 1975
Microfilaments associated with cytoplasmic streaming in Nitella flexilis internodes can be decorated with heavy meromyosin (HMM) from rabbit, both in vitro in cytoplasmic suspensions, and in situ in glycerinated cell segments. The bound HMM consists of clearly discernible, polarized arrowheads in a regular repeat of 360-380 Å that are similar to those ...

Trypanosoma cruzi acidic ribosomal P protein gene family. Novel P proteins encoding unusual cross-reactive epitopes.

The Journal of Immunology, 1993
Abstract We have cloned and characterized cDNA molecules that encode members of the acidic ribosomal protein family (TcP proteins) from the protozoan parasite Trypanosoma cruzi. These proteins have been shown to be antigenic in individuals with T. cruzi infection. Unlike other known eukaryotic cells, T.

Microtubule Proteins and P-Proteins

1982
There are no known functional or structural relationships between tubulins and P-proteins, even though both groups of proteins share the general characteristic of appearing as linear macromolecular assemblies. After actin, tubulin is possibly the second most commonly occurring protein of the non-specialized eukaryote cell; P-protein on the other hand ...

P-Protein in sieve elements

Planta, 1973
The ultrastructure of P1 and P2 proteins in the sieve elements of Heracleum mantegazzianum is described. P1-protein tubules are closely associated with stacks of membranes, are often linked by short cross-bridges, and occasionally display a hexagonal packing.

Fine structure of P-protein filaments from Ricinus communis

Planta, 1973
Exudate from the phloem of Ricinus communis L. was negatively stained, examined in the electron microscope, and the filamentous components compared with those in fixed, sectioned material. In the exudate, two main fibrillar components were observed. One component has a diameter of 20±0.35 (standard error) nm, the other of 14.1±0.34 nm.

P-Protein Trafficking Through Plasmodesmata

1999
Phloem tissue in flowering plants has a distinctive cellular composition in which the conducting elements are a complex of two unique cell types, sieve elements (SE) and companion cells (CC), that are developmentally related and functionally dependent upon one another.

Autoantibodies to ribosomal P proteins in systemic lupus erythematosus

Joint Bone Spine, 2002
Autoantibodies to ribosomal P proteins (anti-P) are directed against three ribosomal phosphoproteins (P0, P1, and P2) and are believed to be specific markers for systemic lupus erythematosus (SLE), particularly with neuropsychiatric manifestations. The objective of this study was to determine the rate of occurrence and clinical significance of anti-P ...
