What pLDDT means and how to read it

Function

Component of the subcortical maternal complex (SCMC), a multiprotein complex that plays a key role in early embryonic development (PubMed:18804437, PubMed:19376971, PubMed:25208553, PubMed:28992324, PubMed:29125140, PubMed:31575650, 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:31575650, PubMed:37922900, PubMed:41845018, PubMed:41917274, PubMed:41986725). They are required to store maternal proteins critical for embryonic development, such as ribosomal proteins, cytoskeletal tubulins and proteins controlling epigenetic reprogramming of the…

Subunit structure

Component of the subcortical maternal complex (SCMC), at least composed of NLRP5, KHDC3, OOEP and TLE6 (PubMed:18057100, PubMed:18804437, PubMed:28992324, PubMed:37922900, PubMed:38177687). Component of cytoplasmic lattices, at least composed of PADI6, NLRP4F, NLRP5, NLRP14, TLE6, KHDC3, OOEP and ZBED3 (PubMed:41845018, PubMed:41917274, PubMed:41986725). Cytoplasmic lattices form a filamentous…
