WormMine: ExpressionPattern Expr979

• Pattern: kettin RNA is present in the pharyngeal, body wall, and anal depressor muscles. Expression in these muscles is particularly pronounced in larvae and hermaphrodites, relative to that seen in male adults. Kettin RNA is also detected in male-specific structures in the tail.
• Primary Identifier: Expr979
• Remark: F54E2 The gene: kettin is located on cosmid F54E2 and R05D8, the actual predicted open reading frame is not mentioned in the article. Sequence: R05D8
