Abstract:
The Caenorhabditis elegans HMX/NKX MLS-2 transcription factor was previously shown to play sequential roles in AWC general identity and the stochastic AWCON/AWCOFF subtype choice during embryogenesis. Here we analyze the expression pattern of endogenous mls-2 during AWC development using mNeonGreen (mNG) knock-in strains. Similar to transgenic GFP::MLS-2, functional mNG::MLS-2 knock-in displayed nuclear localization in AWC precursor cells but was not observed in AWC during the later embryonic stage. These results suggest that the expression of mls-2 is below the detectable level and/or the stability of MLS-2 protein is very low in AWC cells.
