¹ HS: ≤30 mol % cysteine; UHS: >30 mol % cysteine; HGT: 35-60 mol % of glycine and tyrosine.

² Membership is based on the identification of the gene, and not the protein.

³ Numbers after “+” represent pseudogenes, and numbers of family members having genetic variation reported are shown in the brackets.

⁴ Superscript letters indicate the references from which the genetic information was derived: ^a35, ^b7, ^c29, ^d40, ^e41, ^f42, ^g43, ^h30, ⁱ⁴⁴, ^j3, ^k36, ^l4, ^m45, ⁿ³⁷, ^o26, ^p25, ^q5, ^r23, ^s6, ^t46, ^u38 and ^v39.

⁵ While there are currently only three genes reported in the literature for KAP1, there are four known protein sequences.

⁶ No ovine genes have been identified, despite three protein sequences having been reported ¹⁰,⁴⁷.
