Figure 1. C. elegans RGS-3 Is Expressed in a Subset of Sensory Neurons. (A) Protein structure of RGS-3. The
rgs-3 locus encodes three predicted isoforms (A, B, and C) that differ only in the length of their amino termini. The
vs19 deletion removes coding sequence for the 86 carboxy-terminal amino acids of all three isoforms, as well as ~1.1 kb of 3'-untranslated region downstream of the gene.(B and C) RGS-3::GFP is expressed in (B) seven pairs of sensory neu- rons in the head (ASH, ADL, AWB, AWC, ASI, ASJ, and ASK) and (C) two pairs in the tail (PHA, PHB). Expression is observed throughout development and in adult animals.
