SYCE2 Gene

Name synaptonemal complex central element protein 2
Description The protein encoded by this gene is part of the synaptonemal complex formed between homologous chromosomes during meiotic prophase. The encoded protein associates with SYCP1 and SYCE1 and is found only where chromosome cores are synapsed. [provided by RefSeq, Dec 2012]
Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nThe synaptonemal complex (SC) is essential for proper meiotic progression, where the accurate pairing and recombination of homologous chromosomes depend on a robust structural framework. One of the key components of this framework is the SYCE2 protein, which, together with TEX12, forms a highly stable, constitutive complex that nucleates the assembly of the SC central element. Biochemical analyses have revealed that SYCE2 engages in both homotypic and heterotypic interactions—forming a tetramer that associates with TEX12 dimers into an equimolar hetero‐octamer—thereby driving the initial steps in SC formation."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}, {"type": "p", "children": [{"type": "t", "text": "\nHigh-resolution structural studies, including X-ray crystallography, have further elucidated the molecular architecture underlying SYCE2’s function. These analyses indicate that the fundamental building blocks are 2:2 coiled-coil dimers, which further dimerize into 4:4 hetero-oligomers. These oligomers then interact both end-to-end and laterally, assembling into 10-nm fibers that intertwine into bundled 40-nm micrometer-long fibers. Remarkably, the hierarchical assembly mechanism mirrors that of cytoskeletal intermediate filaments, providing the SC with the flexibility and strength required for chromosome synapsis."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": ""}, {"type": "p", "children": [{"type": "t", "text": "\nCombined, these studies offer a comprehensive view of SYCE2’s role as a molecular scaffold within the SC. By orchestrating the formation of higher-order filamentous structures, SYCE2 not only underpins the architecture of the SC’s central element but also facilitates the elongation of the SC along the length of meiotic chromosomes—a process critical for ensuring homologous recombination and accurate chromosomal segregation. These mechanistic insights into SYCE2 function enhance our understanding of the cytological basis of fertility and open avenues for investigating the molecular origins of meiotic errors."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}]}]}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Owen R Davies, Joseph D Maman, Luca Pellegrini "}, {"type": "b", "children": [{"type": "t", "text": "Structural analysis of the human SYCE2-TEX12 complex provides molecular insights into synaptonemal complex assembly."}]}, {"type": "t", "text": " "}, {"type": "i", "children": [{"type": "t", "text": "Open Biol (2012)"}]}, {"type": "t", "text": " DOI: "}, {"type": "a", "children": [{"type": "t", "text": "10.1098/rsob.120099"}], "href": "https://doi.org/10.1098/rsob.120099"}, {"type": "t", "text": " PMID: "}, {"type": "a", "children": [{"type": "t", "text": "22870393"}], "href": "https://pubmed.ncbi.nlm.nih.gov/22870393"}]}, {"type": "r", "ref": 2, "children": [{"type": "t", "text": "James M Dunce, Lucy J Salmon, Owen R Davies "}, {"type": "b", "children": [{"type": "t", "text": "Structural basis of meiotic chromosome synaptic elongation through hierarchical fibrous assembly of SYCE2-TEX12."}]}, {"type": "t", "text": " "}, {"type": "i", "children": [{"type": "t", "text": "Nat Struct Mol Biol (2021)"}]}, {"type": "t", "text": " DOI: "}, {"type": "a", "children": [{"type": "t", "text": "10.1038/s41594-021-00636-z"}], "href": "https://doi.org/10.1038/s41594-021-00636-z"}, {"type": "t", "text": " PMID: "}, {"type": "a", "children": [{"type": "t", "text": "34373646"}], "href": "https://pubmed.ncbi.nlm.nih.gov/34373646"}]}]}]}
