Fig. 1From: Clocks do not tick in unison: isolation of Clock and vrille shed new light on the clockwork model of the sand fly Lutzomyia longipalpis Schematic representation of L. longipalpis Clk and vri genes. The coding region of L. longipalpis Clk gene includes 8 exons and 7 introns, while L. longipalpis vri contains 3 exons and 2 introns. The numbers above the exons represent the position where they start, based on the coding sequence. Introns are presented by Roman numerals. Clk intron sizes are as follows: I (62 bp), II (398 bp), III (497 bp), IV (283 bp), V (357 bp), VI (72 bp), VII (538 bp). For vri, intron sizes are: I (11139 bp) and II (969 bp). Functional domains are colored in green (bHLH), yellow (PAS) and purple (poly-Q) for Clk, and in blue (bZIP) for vri Back to article page
