    A male Drosophila that is not successful in courtship will reduce his courtship efforts in the next encounter with a female. This courtship suppression persists for more than 1 h in wild-type males. The Btk29AficP mutant males null for the Btk29A type 2 isoform, a fly homolog of the nonreceptor tyrosine kinase Btk, show no courtship suppression, while Btk29A hypomorphic males exhibit a rapid decline in courtship suppression, leading to its complete loss within 30 min. The males of a revertant stock or Btk29AficP males that are also mutant for parkas, a gene encoding the presumptive negative regulator of Btk29A, exhibit normal courtship suppression. Since another behavioral assay has shown that Btk29AficP mutants are sensitization-defective, we hypothesize that the mutant flies are unable to maintain the neural excitation state acquired by experience, resulting in the rapid loss of courtship suppression.
