Sažetak
Although your high school biology teacher might not have told you, cells are like nightclubs. They have to make sure the right individuals come in and that the bad individuals— those who might disrupt the normal activity inside the club— stay out. To that end, both nightclubs and cells employ “ bouncers” who prevent unwanted characters from entering. For nightclubs the undesirable character could be a drunk ; for cells the undesirable characters are noxious chemicals. And, as in a nightclub, the job of the cellular “ bouncer” is to prevent any bad players from entering and to throw them out if they should happen to get in. The cellular bouncers are efflux transporter proteins belonging to the ABC superfamily, one of the largest families encoded in the human genome. They sit in the membrane of cells, possess a common ATP binding region referred to as the ATP Binding Cassette (hence, “ ABC transporters” ) and are present in all organisms, from bacteria to human. In many cases, these transporters act as a first line of defense, preventing toxic chemicals from entering the cell. However, if a compound is not recognized by these transporters, or if it overwhelms the transporter capacity and enters the cytoplasm, detoxifying enzymes in the cell may modify the chemical to a more hydrophilic form. In this case, related cellular bouncers can again come into play, effluxing the modified products out of the cell.
