This antibody reacts with normal gastrointestinal epithelium as well as gastrointestinal and breast tumors, resulting in a cytoplasmic staining pattern.
Various cellular organelles and vesicles are transported along the microtubules in the cytoplasm. Likewise, membrane recycling of the endoplasmic reticulum (ER), Golgi assembly at the microtubule organizing center, and alignment of lysosomes along microtubules are all related processes. The transport of organelles requires a special class of microtubule-associated proteins (MAPs). One of these is the molecular motor kinesin an ATPase that moves vesicles unidirectionally toward the plus end of the microtubule. Another such MAP is kinectin, a large integral ER membrane protein. Antibodies directed against kinectin have been shown to inhibit its binding to kinesin.
