The rates at which [14.sup]C-labeled amino acids were incorporated into nascent peptides (i.e.,
polyribosome fraction, as in Fig.

Fragile-X mental retardation protein (FMRP) is a protein involved in ferrying RNA transcripts to
polyribosomes located at sites of protein synthesis.
Common findings were dilated stacks of rough endoplasmic reticulum,
polyribosomes, randomly distributed intermediate filaments, and rare collagen secretion granules (Fig 5).
The cytoplasm of endotheliocyte is also differed by extreme enlightenment; there are few
polyribosomes in it.
Similar to some data, the current investigation showed that C[Cl.sub.4] toxicity resulted in reduction of liver total protein content in C[Cl.sub.4]-treated rats suggesting the disruption and disassociation of
polyribosomes from endoplasmic reticulum following C[Cl.sub.4] administration (Clawson, 1989).

Metabotropic glutamate receptor-initiated translocation of protein kinase p90rsk to
polyribosomes: a possible factor regulating synaptic protein synthesis.
The cytoplasm also contained some mitochondria, granular endoplasmic reticulum, single ribosomes and
polyribosomes, and Golgi complexes (Figure 5).
Also, the other cellular alterations such as decreased protein content, increased ribonuclease activity, protein hydrolysis, hydrogen peroxide concentration and dissociation of
polyribosomes are also known to occur in plants exposed to water stress [15,22].

FMRP associates with
polyribosomes as an mRNP, and the 1304N mutation of severe fragile X syndrome abolishes this association.
