Enables protein kinase C binding activity and small GTPase binding activity. Involved in several processes, including establishment of mitotic spindle localization; gonad development; and polarity specification of anterior/posterior axis. Located in P granule and cell cortex. Is extrinsic component of cytoplasmic side of plasma membrane. Expressed in several structures, including ABa; EMS; Psub2; Psub3; and excretory cell. Is an ortholog of human PARD6B (
par-6 family cell polarity regulator beta).
