Identifiers and Description
Gene Model Identifier
ASI2 (Anlagen Stage Induced )
PreTt08799 | 15.m00510 | 3697.m00221
Similar to anlagen stage induced protein 1 (ASI1); protein of unknown function; gene is located adjacent to the ASI1 gene
ASI2 is a gene regulating endocycling in Tetrahymena thermophila. Though nonessential for vegative growth, it is upregulated after meiosis and is involved in the creation of a new MAC. Introduced via transduction with ASI2-GFP plasmid to establish parental cells that showed transcription of ASI2 occurs both in MAC and parental cells at conjugation.
Regulation & Expression:
The Tetrahymena gene ASI1 (anlagen stage induced 1) was isolated from a cDNA library of genes that are up-regulated during development of the macronuclear anlagen. As its name implies, the abundance of ASI2 mRNA peaks at 9 h of mating, early in macronuclear anlagen development.
