Figure 1From: Phylogenetic and functional analysis of the Cation Diffusion Facilitator (CDF) family: improved signature and prediction of substrate specificityCDF signature. Sequence logo representation of the modified signature. The height of amino acid symbols is related to their conservation in the multiple alignment. Amino acid position refers to PtdMTP1. The hypothetical secondary structure (TMDs II and III) is shown below.Back to article page
