CLUSTAL alignment of FRL2 and FRI. Polymorphisms in the amino acid sequence of the FRL2 proteins are indicated with the # sign. The underlined sequences above and below the alignment indicate the predicted coiled-coil domains of FRL2 and FRI, respectively. The COILS software at http://www.ch.embnet.org/software/COILS_form.html was used to predict the coiled-coil domains in FRL2 and FRI (Lupas et al., 1991).
