Translocation is the human action of moving an organism from one area and releasing it in another. In terms of wildlife conservation , its objective is to improve the conservation status of the translocated organism or to restore the function and processes of the ecosystem the organism is entering.
The translocon (also known as a translocator or translocation channel) is a complex of proteins associated with the translocation of polypeptides across membranes. [1] In eukaryotes the term translocon most commonly refers to the complex that transports nascent polypeptides with a targeting signal sequence into the interior (cisternal or lumenal) space of the endoplasmic reticulum (ER) from ...
Chromosomal reciprocal translocation of the 4th and 20th chromosome. In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced translocation, with two main types: reciprocal, and Robertsonian translocation.
Translocation may refer to: Chromosomal translocation, a chromosome abnormality caused by rearrangement of parts Robertsonian translocation, a chromosomal rearrangement in pairs 13, 14, 15, 21, and 22; Nonreciprocal translocation, transfer of genes from one chromosome to another; PEP group translocation, a method used by bacteria for sugar uptake
In biology, translation is the process in living cells in which proteins are produced using RNA molecules as templates. The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time.
This translocation process is actively dependent on the Ran protein, although the specific mechanism is not yet well understood. Some particularly commonly transcribed genes are physically located near nuclear pores to facilitate the translocation process.
Translocation of Domestic animals [ edit ] An early example is the spread of domesticated zebu , a species of cattle, which originated in South Asia and was introduced to Mesopotamia and Arabia in 3000 BCE, then on to the central plains of Asia and China in 1500 BCE, and Africa by 600 BCE. [ 3 ]
A stromal transit peptide sequence (yellow rectangle) is exposed on the translated protein in the cytosol, which signals the ribosome and translocons to begin translocation into the stroma. Once in the stroma, signal peptidases cleave the first peptide sequence only to reveal a Thylakoid transit peptide sequence (blue rectangle).
