Synaptonemal complex protein 2 (SYCP2) N-terminal region contains two separate subdomains an ARLD (armadillo-repeat-like domain) and an SLD (Spt16M-like domain). The SLD structure is highly similar to the middle domain of the histone chaperone FACT. It consists of a twisted ten-stranded beta-sheet flanked by two helices. Since the SLD domain structurally resembles Spt16M, which is known as the well-recognized histone protein H2A-H2B; it is speculated that the SLD may be involved in chromatin binding [1].	Domain
