The <i>unc-41</i> gene products are differentially expressed in the <i>C. elegans</i> nervous system.

<p>Animals expressing the <i>Punc-41A::</i>NLS-CFP (green) and <i>Punc-41B::</i>NLS-YFP (red) transgenes were imaged on a confocal microscope. An L1 larva is shown in the left column (panels A, C, and E). One of the six GABA motor neurons (DD) is indicated. The animal’s head is in the upper left of the image, and the animal is positioned with its ventral surface on the inside of the arc (scale bar is 10 µm). Shown in the right column (panels B, D, and F) is the head region of an adult hermaphrodite. The nerve ring (nr), dorsal nerve cord (dnc), and ventral nerve cord (vnc) are indicated for reference. Anterior is to the left, ventral is down, and the bar is 10 µm.
