Is predicted to encode a protein with the following domains: N-terminal of Par3 and HAL proteins; PDZ domain; PDZ domain; Par3/HAL, N-terminal; and PDZ superfamily. Is an ortholog of C. elegans par-3
. In C. elegans, par-3
is involved in several processes, including establishment of mitotic spindle orientation; gonad development; and polarity specification of anterior/posterior axis.
