Is predicted to encode a protein with the following domains: Ankyrin repeats (3 copies); Ankyrin repeat-containing domain superfamily; KRIT, N-terminal NPxY motif-rich region; Ankyrin repeat; Domain of unknown function DUF3447; and NUDIX, or N-terminal NPxY motif-rich, region of KRIT. Is an ortholog of C. elegans kri-1. In C. elegans, kri-1 is involved in positive regulation of gene expression.
