The human protein acid transporter (hPAT1) is 5585 base pairs long and codes for a protein 476 amino acids long. The transporter has nine transmembrane regions where the amino terminus faces the cytoplasm. The rat protein acid transporter (rPAT1) has been widely studied and an 85% amino acid sequence match was found between hPAT1 and rPAT1.
Intracellular transport is the movement of vesicles and substances within a cell. Intracellular transport is required for maintaining homeostasis within the cell by responding to physiological signals. [1] Proteins synthesized in the cytosol are distributed to their respective organelles, according to their specific amino acid’s sorting ...
Kojic acid is an organic compound with the formula HOCH 2 C 5 H 2 O 2 OH. It is a derivative of 4-pyrone that functions in nature as a chelation agent produced by several species of fungi, especially Aspergillus oryzae , which has the Japanese common name koji .
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 .
Protein targeting or protein sorting is the biological mechanism by which proteins are transported to their appropriate destinations within or outside the cell. [ 1 ] [ 2 ] [ note 1 ] Proteins can be targeted to the inner space of an organelle , different intracellular membranes , the plasma membrane , or to the exterior of the cell via secretion .
A membrane transport protein is a membrane protein involved in the movement of ions, small molecules, and macromolecules, such as another protein, across a biological membrane. Transport proteins are integral transmembrane proteins ; that is they exist permanently within and span the membrane across which they transport substances.
Exocytosis (/ ˌ ɛ k s oʊ s aɪ ˈ t oʊ s ɪ s / [1] [2]) is a form of active transport and bulk transport in which a cell transports molecules (e.g., neurotransmitters and proteins) out of the cell (exo-+ cytosis). As an active transport mechanism, exocytosis requires the use of energy to transport material.
At the end, the end of a signal pathway leads to the regulation of a cellular activity. This response can take place in the nucleus or in the cytoplasm of the cell. A majority of signaling pathways control protein synthesis by turning certain genes on and off in the nucleus. [45]
