The identified novel gene T37L in mosquitoes. (a) T37L protein contains two putative functional protein-protein binding domains: RING-finger domain and MATH domain. (b). Partial amino acid alignment of T37L genes in six mosquito species. (c) Conservative "tail-to-tail" organization between the T37L and a Vtg gene in mosquitoes. The open boxes represent coding sequence and the filled box represents intron sequence. The intergenic region sizes are indicated. (d) Transcriptional expression of T37L in Culex tarsalis. Accession numbers are: Culex pipiens, NZ_AAWU01017726; Aedes aegypti, AY373377; Aedes polynesiensis, AY691320; Ochlerotatus triseriatus, AY691323; Anopheles gambiae, AAAB01008880.
