As a member of the subcortical maternal complex (SCMC), plays an essential role for zygotes to progress beyond the first embryonic cell divisions via regulation of actin dynamics (By similarity). Required for the formation of F-actin cytoplasmic lattices (CPL) in oocytes, which in turn are responsible for symmetric division of zygotes via the regulation of mitotic spindle formation and positioning (By similarity). Required for the localization of cortical granules to the cortex of oocytes, via association with the cortical actin scaffold (By similarity). Required for cortical actin clearance prior to oocyte exocytosis (By similarity). Involved in regulating post-fertilization Ca(2+) release and endoplasmic reticulum (ER) storage via regulation of ER cellular localization (By similarity). May be involved in the localization of mitochondria to the cytoplasm and perinuclear region in oocytes and early stage embryos, independent of its role in CPL formation (By similarity). Component of the subcortical maternal complex (SCMC), at least composed of NLRP5, KHDC3, OOEP, and TLE6 (By similarity). Within the complex, interacts with OOEP, KHDC3 and TLE6 (By similarity). The SCMC may facilitate translocation of its components between the nuclear and cytoplasmic compartments (By similarity). As part of the SCMC interacts with the SCMC-associated protein ZBED3 (By similarity). As part of the SCMC interacts with the SCMC-associated protein CFL1/Cofilin-1 (By similarity). Interacts with PRKCE (By similarity). Interacts with TUBB3 at cytoskeleton microtubules (By similarity). Oocyte-specific. Phosphorylated by PRKCE. Belongs to the NLRP family.
