WormMine: ExpressionPattern Expr13725

• Pattern: TRA-1 is expressed broadly throughout the entire nervous system. Unexpectedly, TRA-1 expression was found to be essentially undetectable in postmitotic neurons in early larval stages (L1, L2), suggesting that at these early larval stages the nervous system may not yet have acquired sexually dimorphic features. We found TRA-1 expression in postmitotic neurons of the nervous system to commence at the L3 stage, peak at the L4 stage, and persist well into adulthood.
