Fig. 6. Model for the distribution of SYCE1 and CESC1 within the synaptonemal complex. Dimers or multimers of CESC1 and SYCE1 associate with the N-terminal region of SYCP1. This interaction could confer additional robustness and flexibility to the SC, important for the development of recombination events. C, carboxyl-terminus; CE, central element; LE, lateral element; N, amino-terminus.
