Docking is the intentional removal of part of an animal's tail or, sometimes, ears. The term cropping is more commonly used in reference to the cropping of ears, while docking more commonly—but not exclusively—refers to the tail; the term tailing is used, also. The term has its origins in the living flesh of the tail, commonly known as the ...
Connexon. In biology, a connexon, also known as a connexin hemichannel, is an assembly of six proteins called connexins that form the pore for a gap junction between the cytoplasm of two adjacent cells. This channel allows for bidirectional flow of ions and signaling molecules. [1] The connexon is the hemichannel supplied by a cell on one side ...
In the field of molecular modeling, docking is a method which predicts the preferred orientation of one molecule to a second when a ligand and a target are bound to each other to form a stable complex. [1] Knowledge of the preferred orientation in turn may be used to predict the strength of association or binding affinity between two molecules ...
The Kozak consensus sequence (Kozak consensus or Kozak sequence) is a nucleic acid motif that functions as the protein translation initiation site in most eukaryotic mRNA transcripts. [1] Regarded as the optimum sequence for initiating translation in eukaryotes, the sequence is an integral aspect of protein regulation and overall cellular ...
Docking The loaded synaptic vesicles must dock near release sites, however docking is a step of the cycle that we know little about. Many proteins on synaptic vesicles and at release sites have been identified, however none of the identified protein interactions between the vesicle proteins and release site proteins can account for the docking ...
The Rab family of proteins is a member of the Ras superfamily of small G proteins. [1] Approximately 70 types of Rabs have now been identified in humans. [2] Rab proteins generally possess a GTPase fold, which consists of a six-stranded beta sheet which is flanked by five alpha helices. [3] Rab GTPases regulate many steps of membrane ...
Last universal common ancestor. The last universal common ancestor (LUCA) is the hypothesized common ancestral cell from which the three domains of life, the Bacteria, the Archaea, and the Eukarya originated. The cell had a lipid bilayer; it possessed the genetic code and ribosomes which translated from DNA or RNA to proteins.
Xenotransplantation (xenos- from the Greek meaning "foreign" or strange [1][2]), or heterologous transplant, is the transplantation of living cells, tissues or organs from one species to another. [3] Such cells, tissues or organs are called xenografts or xenotransplants. It is contrasted with allotransplantation (from other individual of same ...
