The de novo protein synthesis theory of memory formation is a hypothesis about the formation of the physical correlates of memory in the brain. It is widely accepted that the physiological correlates for memories are stored at the synapse between various neurons .
Specifically, it is unclear whether protein synthesis takes place in the postsynaptic cell body or in its dendrites. [39] Despite having observed ribosomes (the major components of the protein synthesis machinery) in dendrites as early as the 1960s, prevailing wisdom was that the cell body was the predominant site of protein synthesis in ...
Watson and Alexander Rich discussed in the PNAS, saying, "We shall not be able to check a structural relationship between RNA and protein synthesis or between RNA and DNA until we know the structure of RNA." [5] Evidences had been accumulating since the 1940s that protein synthesis occurs simultaneously with increased level of RNA in the cytoplasm.
Protein synthesis plays an important role in the formation of new memories. Studies have shown that protein synthesis inhibitors administered after learning, weaken memory, suggesting that protein synthesis is required for memory consolidation. Additionally, reports have suggested that the effects of protein synthesis inhibitors also inhibit ...
FMR1 (Fragile X Messenger Ribonucleoprotein 1) is a human gene [5] that codes for a protein called fragile X messenger ribonucleoprotein, or FMRP. [6] This protein, most commonly found in the brain, is essential for normal cognitive development and female reproductive function.
The Britten–Davidson model, [1] [2] also known as the gene-battery model, [3] is a hypothesis for the regulation of protein synthesis in eukaryotes.Proposed by Roy John Britten and Eric H. Davidson in 1969, the model postulates four classes of DNA sequence: an integrator gene, a producer gene, a receptor site, and a sensor site.
Protein synthesis is a very similar process for both prokaryotes and eukaryotes but there are some distinct differences. [1] Protein synthesis can be divided broadly into two phases: transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a molecule called messenger RNA (mRNA).
Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding. Proteins are made from amino acids. In humans, some amino acids can be synthesized using already existing intermediates. These amino ...
