a
Across 220 organisms with sequenced genomes, the fractions of the total found to possess an Srx are given in parentheses. Groups containing any members with an Srx-encoding gene are highlighted in bold.
b
Searches of the Anolis carolinensis genome did not yield an Srx sequence, but that of Ophiophagus hannah (king cobra) did.
c
Frogs from the genus Xenopus. Additional searches yielded no amphibian Srx-possessing representatives.
d
The mosquito Anopheles gambiae had no Srx, but two other mosquitos, Aedes aegypti and Culex quinquefasciatus, possessed an Srx gene.
