Is predicted to encode a protein with the following domains: U2A'/phosphoprotein 32 family A, C-terminal; Leucine Rich repeats (2 copies); Leucine-rich repeat; Leucine-rich repeat, typical subtype; Leucine rich repeat 4; and Leucine-rich repeat domain superfamily. Is an ortholog of C. elegans sds-22. In C. elegans, sds-22 is involved in negative regulation of centriole replication.
