WebFeb 27, 2024 · The CFTR is a transmembrane chloride (Cl -) and bicarbonate (HCO 3-) ion channel that is expressed in the apical membranes of the epithelial cells of multiple exocrine organs, where it regulates salt and fluid homeostasis ( Linsdell, 2014 ). WebAn mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence. This process is called translation. Prokaryotes lack a nucleus, so their mRNAs are transcribed in the cytoplasm and can be translated by ribosomes immediately. Image credit: OpenStax Biology.

WebRibosomes provide the scaffolding on which tRNAs interact with mRNA during translation of an mRNA sequence to a chain of amino acids. A ribosome has three binding sites, each of which has a distinct function in the tRNA-mRNA interactions. WebAll proteins, including CFTR, are made of building blocks called amino acids that are linked together into a long chain. The protein-building instructions spelled out in the CFTR gene tell the cell which of the 20 available amino acids to use at each position in the chain.
