Functions
• The main functions of the endoplasmic reticulum are the facilitation of protein folding and the transport of synthesized proteins in sacs (cisternae).The endoplasmic reticulum can be referred to as the transportation system of an eukaryotic cell.
• The ER is also involved with the insertion of proteins into its membrane, glycosylation involving the attachment of oligosaccharides, disulfide bond formation, disulfide rearrangement and drug metabolism.
• Functions vary, depending on the type of endoplasmic reticulum and the type of cell in which it resides.

What is the involvement of organelles in protein production?

It also contains ribosomes; however most of its proteins are encoded by genes contained in the host cell nucleus, with the protein products transported to the chloroplast.
• Within the stroma are stacks of thylakoids, the sub-organelles, which are the site of photosynthesis.
• Photosynthesis takes place on the thylakoid membrane; as in mitochondrial oxidative phosphorylation, it involves the coupling of cross-membrane fluxes with biosynthesis via the dissipation of a proton electrochemical gradient.
Link between Structure and Function:
• The cell nucleus controls the hereditary characteristics of an organism and is responsible for the protein synthesis, cell division, growth and differentiation.
• It is able to do this because it stores hereditary material, referred to as chromatins, in the form of long and thin DNA (deoxyribonucleic acid) strands.

, a mutation in the Kit protein:A separate mutation, called (Ws) knocksout the , a tyrosine kinase transmembrane receptor,which is produced by the c-kit gene. The mutation is a 12-basedeletion in the c-kit gene (Tsujimura 1991). The kitprotein has a wide variety of functions! Kit is involved in thedevelopment of blood stem cells (precursors to red and white bloodcells), melanoblasts, and primordial germ cells, and melanoblastmigration (Horie 1991). So knocking out the kit proteinwill have a variety of effects, including: depigmentation of certainareas (up to and including entirely white with black eyes), andsometimes anemia, a deficiency of mast cells (and thereforedeficiencies in histamine and serotonin), reproductive problems anddeafness (Kitamura 1994, Hoshino 2000, Sugimoto1995).

polyribosomes or polysomes is associated with protein synthesis.

This attachment of aphosphate group to the carrier molecule causes a conformational changein (or achange in the shape of ) the protein so that a channel opens between theinside and outside of the cell membrane.

These membranes create five distinct compartments within the mitochondria; the outer membrane (associated with the ER membrane), the intermembrane space, the inner membrane, the cristae (creates a larger surface area and enhances the inner membrane's ability to produce ATP) and the matrix.
• The large amount of proteins in the mitochondria's inner membrane reflect its function; production of the cells energy (ATP).
• A small fraction of the cell's genes are located instead in the mitochondria.

More information about the Inner membrane:
The inner mitochondrial membrane contains proteins with five types of functions:
1. Those that perform the redox reactions of oxidative phosphorylation
2. ATP synthase, which generates ATP in the matrix
3. Specific transport proteins that regulate metabolite passage into and out of the matrix
4. Protein import machinery.
5. Mitochondria fusion and fission protein.

A Cell is the smallest structural and functional unit of the body

For the first time we report about the presence of genes in human RBCs encoding initiation, activation and regulation of transcription and translation (for instance RNA polymerises I,II,III, zinc/PHD finger- DNA-binding proteins, cysteinyl, lysyl-tRNA synthetase), important RNA-stabilising factor - poly(A) binding protein, anti-apoptotic proteins (for instance beclin 1, reticulon 4, BCL2, IAP) together with genes for RNA degradation (for example ribonuclease T2) as well as genes encoding typical apoptotic proteins such as cyclooxygenase, apoptotic protease activating factor, caspase 8. Other authors were able to show a protein synthesis in human platelets by megakaryocyte-derived mRNAs . The finding of RNA in anucleate cells like erythrocytes support the idea of nucleus independent protein synthesis and supports data about possible mechanism of globin m-RNA stability in human RBCs.

Which is the Basis of all the functions of the body

Isopycnic sucrose density gradients of homogenates from carrot root tissue were analyzed radiochromatographically, radiochemically, and photometrically for the presence of hydroxyproline residues. Significant amounts were found in endoplasmic reticulum (ER), Golgi apparatus (GA) and plasma membrane (PM) fractions as designated by the presence of marker enzymes for these membranes. Some hydroxyproline-containing macromolecules could be detected in the soluble cytoplasm (cytosol) but this was interpreted as an artefact due to homogenization. Hydroxyproline-rich polymers can be released from a mixed ER/PM fraction by freezing and thawing in water. The PM-associated hydroxyproline polymer is suggested to be an arabinogalactan protein rather than cell wall extensin. Nevertheless, the polypeptides of both glycoproteins are considered as being synthesized at the ER and transported via the GA to the PM.

Understanding of molecular mechanisms governing the enucleating phenomena of human erythrocytes is of major importance in both fundamental and applied studies. Total RNA (n=7) from human RBCs (purity of erythrocyte preparation >99,99%) was tested using 2100 Bioanalyzer (, USA), and transcribed to cDNA. Microarray analysis was performed with the Human Genome Focus GeneChip (, USA), containing 8500 transcripts corresponding to 8400 human genes. Here we report that human RBCs contain typical eukaryotic RNA with 28S- and18S-rRNA standard bands. Microarray studies revealed the presence of transcripts of 1019 different genes in erythrocytic RNA. Gene Ontology analysis recognized 859 genes involved in general biological processes: 529 genes for cellular metabolism, 228 genes for signal transduction, 104 genes for development, 107 genes for immune response, 62 genes for protein localization, 53 genes for programmed cell death, and 5 genes for autophagy. A number of genes responsible for transcription, translation, RNA-stabilisation as well as for apoptosis and anti-apoptosis have been identified for the first time in circulating human RBCs. The presented data shed new light on the genetic determination of erythropoiesis, apoptosis and may have implications on the pathophysiology and diagnosis of various diseases involving red blood cells.

These common features are:

DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes

Plasma membrane, a phospholipid bilayer with proteins that separates the cell from the surrounding environment and functions as a selective barrier for the import and export of materials

Cytoplasm, the rest of the material of the cell within the plasma membrane, excluding the nucleoid region or nucleus, that consists of a fluid portion called the cytosol and the organelles and other particulates suspended in it
