WormMine: ExpressionPattern Expr2831

• Pattern: Expression was first observed in early embryos at cell peripheries and in a punctate pattern throughout embryos. Later, expression was observed in larvae in the nerve ring and many neurons of the nerve ring ganglia, pharyngeal muscle, and ventral cord and many neurons in the tail ganglia and hypodermis. Highest expression levels were observed in L4 larvae and in adult animals. Expression in larvae and in adults was also evident in the pharyngeal muscle. Expression was also observed in the dorsal nerve cord and in sublateral processes . In addition, occasional expression was observed throughout the intestine (particularly in the posterior intestine), vulval muscle, head muscle, in sperm, tonofilaments, and in vulval cells. With the exception of the pharyngeal muscle, expression levels in muscle were generally extremely low such that only rare animals (10%) showed weak expression. The CAN cell bodies and associated canals were observed to express GFP-tagged EGL-30 in most animals. The HSN cell bodies and the VC4 and VC5 neuronal cell bodies also occasionally expressed EGL-30 (10%), on the basis of proximity to the vulva. Other cell bodies in the ventral nerve cord were also observed to occasionally express GFP. Weak or occasional expression in other muscle-cell types, sperm, intestine, tonofilaments, and vulval cells indicates the possibility that EGL-30 might have an almost ubiquitous expression pattern.
• Primary Identifier: Expr2831
• Subcellular Localization: Expression was observed in early embryos at cell peripheries and in a punctate pattern throughout embryos. In the nervous system, expression was observed in cell bodies and in neural processes. However, the highest expression was observed in the axons of the nerve ring.
