Function

NALP5_MOUSE Component of the subcortical maternal complex (SCMC), a multiprotein complex that plays a key role in early embryonic development (PubMed:11062459, PubMed:18804437, PubMed:25208553, PubMed:37922900). The SCMC complex is a structural constituent of cytoplasmic lattices, which consist in fibrous structures found in the cytoplasm of oocytes and preimplantation embryos (PubMed:37922900). They are required to store maternal proteins critical for embryonic development, such as proteins that control epigenetic reprogramming of the preimplantation embryo, and prevent their degradation or activation (PubMed:37922900). Required for the localization of cortical granules to the cortex of oocytes, via association with the cortical actin scaffold (PubMed:31118423). Required for cortical actin clearance prior to oocyte exocytosis and prevention of polyspermy (PubMed:31118423). Involved in regulating post-fertilization Ca(2+) release and endoplasmic reticulum storage (ER) storage via regulation of cellular localization (PubMed:24374158). 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 (PubMed:22357545).^{[1] [2] [3] [4] [5] [6] [7]}
