The 30.5 kDa family of culicine proteins. A) Clustal alignment. The Culex tarsalis proteins are identified by their Ctar-prefix. The remaining sequences are named with the first three letters from the genus name followed by two letters from the species name and by their NCBI protein accession number. The symbols above the alignment indicate: (*) identical sites; (:) conserved sites; less conserved sites. B) Neighbor Joining bootstrapped phylogram of the alignment in A. The Culex tarsalis proteins are marked with a square symbol. The numbers on the branches represent the percent bootstrap support. The bar in the bottom represents 20% amino acid divergence.
