Genetic Descriptionbig1-1/big1-1 (big1-1; II)
MAC Knockins/outs

Gene of InterestBIG1 (big 1)

PublicationsFrankel J, Jenkins LM, Bakowska J, Nelsen EM. 1984b. Mutational analysis of patterning of oral structures in tetrahymena. I. effects of increased size on organization. J Embryol Exp Morphol 82:41-66.
CommentsIncrease in size of cells, number of ciliary rows, and size of oral apparatus. Ciliary rows are disorganized, and 10-20% of oral apparatuses are abnormal, with extra membranelles common.

Highly pleiotropic. The disorganization of the ciliary rows was not mentioned in the brief published description, but is prominent. Expression unform at all temperatures tested.
