Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.
