ain-2 encodes an ubiquitously expressed homolog of AIN-1. (A) Schematic illustration of the structure of
ain-2 (B0041.2) and the
tm1863 mutation. Only one of the three predicted potential alternative splicing forms is shown (wormbase.org). The
tm1863 mutation, which lacks the region indicated, resulted in a truncated protein with a new in-frame ATG at the position indicated. (B) Aligned black regions indicate homologous sequences in AIN-1 and AIN-2. (C) Fluorescence images showing the expression of a functional AIN-2::GFP from a single-copy-integrated transgene. The GFP signal was visible in all tissues examined.
