WormMine: ExpressionPattern Expr13828

• Pattern: sem-4 is expressed in the HSN at L4 coinciding with the onset of differentiation. sem-4 is also expressed in other neurons but not in the ADF serotonergic neuron. SEM-4 is widely expressed inthe embryo in the area were HSN is located, although it is likely to be expressed atthis early stage in HSN, the authors could not unequivocally identify it. sem-4 expression is maintained in HSN after differentiation.
• Primary Identifier: Expr13828
