Component of the subcortical maternal complex (SCMC), a multiprotein complex that plays a key role in early embryonic development (PubMed:26537248). The SCMC complex is a structural constituent of cytoplasmic lattices, which consist in fibrous structures found in the cytoplasm of oocytes and preimplantation embryos (By similarity). 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 (By similarity). Also required for spermatogenesis: regulates spermatogonia proliferation and cell cycle progression, potentially via regulation of cell cycle regulatory genes such as; CEBPB, CEBPA, CSF3, PCNA, and CDK4 (By similarity). Suppresses FOXG1/BF-1-mediated transcriptional repression by inhibiting interaction of the transcriptional corepressor TLE1 with FOXG1 which promotes cortical neuron differentiation (By similarity). Acts as a transcriptional corepressor of NFATC1-mediated gene expression by contributing to PAX6-mediated repression (By similarity). . [Isoform 1]: Component of the subcortical maternal complex (SCMC), a multiprotein complex that plays a key role in early embryonic development. . This is the function of TLE6 (TLE family member 6, subcortical maternal complex member, ENSG00000104953).
