Is predicted to encode a protein with the following domains: Leucine-rich repeat, typical subtype; Leucine-rich repeat; Leucine rich repeat; Leucine Rich Repeat; and Leucine-rich repeat domain superfamily. Is an ortholog of C. elegans let-4. In C. elegans, let-4 is involved in several processes, including epithelial cell development; nematode larval development; and positive regulation of membrane permeability.
