WormMine: ExpressionPattern Expr3814

• Pattern: Immunohistochemical localization using a STA-1-specific antibody readily detected STA-1 protein in pharynx, head ganglia, tail ganglia, ventral nerve cord, embryos, and body muscles.
• Primary Identifier: Expr3814
• Remark: Expression pattern in other life stages was not mentioned in the paper.
• Subcellular Localization: A diffuse staining pattern indicate a largely cytoplasmic localization. This pattern of STA-1 accumulation suggests that it is transcriptionally inactive in the majority of tissues in growing animals. In contrast, detailed analysis of immunostaining patterns in the head ganglia revealed a distinct pattern of nuclear STA-1 accumulation in a few neuronal cells, indicative of activation. Confocal immunostaining analysis of head ganglia identified precise nuclear accumulation of STA-1 in select subsets of neurons.
