SpeciesT. thermophila
Genetic DescriptionjanB-1/janB-1 (janB-1; III)
MAC Knockins/outs
MIC Knockins/outs
Gene of InterestJANB (janus B)

PublicationsCole ES, Frankel J, Jenkins LM. 1988. Interactions between janus and bcd cortical pattern mutants in tetrahymena thermophila. Development Genes and Evolution 197(8):476-89. (emphasizes its interaction with bcd1-1).
