Web24 mrt. 2009 · The recognition of sequence homology occurs with amazing precision. In site-specific recombination, the exchange happens at specific, designated loci recognized by the complex recombination machinery of the cell (involving multiple proteins). In homologous recombination the exchange can occur anywhere. WebThe crystal structure of an E2F4–DP2–DNA complex shows that the DNA-binding domains of the E2F and DP proteins both have a fold related to the winged-helix DNA-binding motif. Recognition of the central c/gGCGCg/c sequence of the consensus DNA-binding site is symmetric, and amino acids that contact these bases are conserved among all known ...

Web15 jun. 2012 · Homologous chromosomes are usually separated at the entrance of meiosis; how they become paired is one of the outstanding mysteries of the meiotic process. Reduction of spacing between homologues makes possible the occurrence of chromosomal interactions leading to homology detection and the formation of bivalents. In many … Web27 sep. 2024 · Homologous recognition may be facilitated by the clustering of telomeres at one pole of the cell, forming the telomere bouquet (see ). During zygotene, chromosomes begin synapsis via the formation of the synaptonemal complex (SC), which consists of axial and central elements [ 33 ].

WebHomologous chromosome pairing requires the formation and repair of meiotic DNA double-strand breaks (DSBs). The topoisomerase-like enzyme SPO11 makes the DSBs, and the recombinase RAD51 and its meiosis-specific paralogue DMC1 are involved in homology recognition and strand invasion. WebHomology modeling treats the template in an alignment as a sequence, and only sequence homology is used for prediction. Protein threading treats the template in an alignment as …

WebRecognition is achieved upon binding of both strands of the incoming dsDNA to each of two ssDNA-binding sites in the filament. The data indicate a physical picture for homology recognition in which the fidelity of the search process is governed by the distance between the DNA-binding sites.
