Is predicted to encode a protein with the following domains: Phosphatidylinositol 3-/4-kinase, catalytic domain; Transcription-associated protein 1; Armadillo-type fold; and Protein kinase-like domain superfamily. Is an ortholog of C. elegans trr-1. In C. elegans, trr-1 is involved in negative regulation of vulval development; positive regulation of growth rate; and reproduction.
