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 ...

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 ...

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.

Selective interference with P protein binding to paramyxovirus nucleocapsids

Virus Research, 1994
We previously observed that some anti-nucleoprotein monoclonal antibodies were able to displace P protein from Sendai virus (SV) nucleocapsid cores. The current work extends that observation by showing that such antibody-mediated P displacement is not unique to Sendai virus nucleocapsids, but can also occur with nucleocapsids of a related human ...

The distribution of P-Protein in mature sieve elements of celery

Planta, 1975
The extent of blocking of sieve-plate pores caused by release of cell turgor was investigated by fixing and processing for electron microscopy a long length of celery (Apium graveolens L.) phloem. Differences in distribution of P-protein within the pores were observed between those cells near the two cut ends, and the central cells.To assess the effect

Association of amyloid P protein with pathology in periodontal tissues

Journal of Oral Pathology & Medicine, 1994
The lesion of chronic periodontitis is characterized by the persistence of perivascular collections of degenerate plasma cells. In this study, immunohistochemical demonstration of amyloid P (AP) component was used to define the distribution of this protein in established periodontitis lesions and in biopsies of non‐destructive marginal gingivitis ...

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 ...

Evaluation of Assays for the Detection of Autoantibodies to the Ribosomal P Proteins

Clinical Immunology, 2000
Sera from systemic lupus erythematosus patients that had antibodies to the ribosomal P proteins were compared in several different assays. The enzyme-linked immunosorbent assay (ELISA) method was compared to the Western immunoblotting method using either affinity purified human or bovine ribosomal P proteins.
