The prokaryotic CFI-box motif was shown in model NF041763 to be a probable protein modification site, first modified on the Cys sidechain and then, most likely cleaved in a manner resembling the CAAX box in eukaryotes. At least 12 otherwise unrelated proteins in Desulfatibacillum aliphaticivorans strain AK-01 (CP001322.1) share the motif at or close to the C-terminal. ACL06505.1 has the CFI motif as the start of a longer tail region. This HMM models that CFI-box-containing tail region. This long form, of the CFI putative sorting signal, in which the CFI motif occurs at the start of a longer homology domain, is here designated the CFI-box-CTERM domain.
