No cell will express the pattern the exact same as another one but the proteins of interest should locate to the same subcellular structures and thanks to that have a similar pattern in the green channel. The other 3 channels help us understand what we are looking at. For example, if the red channel (the microtubule marker) overlaps with the green we can see that the protein of interest is locating to the microtubules.</p>\n\n<p>If it is still unclear, don't hesitate to ask!
