Figure 3From: Adaptive evolution of SCML1in primates, a gene involved in male reproductionGene structure and sequence comparison among SCML1 , SCML2 and SCMH1 . A) SCML1 and SCML2 are both located on the X-chromosome and the transcription directions are indicated by the arrows. B) The protein sequence alignment among the three genes. The SAM domains are highlighted. Sterile alpha motif (SAM) domains are known to exhibit diverse protein-protein interaction modes[57]Back to article page
