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 ...

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 ...

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 the phloem of Cucurbita. I. The development of P-protein bodies.

The Journal of cell biology, 1968
Light and electron microscopical observations of the cells of the phloem of Cucurbita maxima have shown that two distinct types of P-protein bodies are formed: a larger type which arises as fine fibrils and a smaller type which apparently arises as groups of tubules. The tubules of the smaller type of body measure 242 +/- 3.6 (SE) A (n = 48) and appear

P protein in the phloem of Cucurbita. II. The P protein of mature sieve elements.

The Journal of cell biology, 1968
During maturation of sieve elements in Cucurbita maxima Duchesne, the P-protein bodies (slime bodies) usually disperse in the tonoplast-free cell. In some sieve elements the P-protein bodies fail to disperse. The occurrence of dispersal or nondispersal of P-protein bodies can be related to the position of the sieve elements in the stem or petiole.

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 ...
