The cDNA fragments of ostrich (S. camelus, SCA) homologs of chicken Z-linked genes and nucleotide sequence identities among S. triporcatus (STR), ostich and chicken (Gallus gallus, GGA) cDNA fragments.

aACO1, aconitase 1, soluble; ATP5A1, ATP synthase, H+ transporting, mitochondrial F1 complex, alpha subunit, isoform 1, cardiac muscle; CHD1, chromodomain helicase DNA binding protein 1; DMRT1, doublesex and mab-3 related transcription factor 1; FER, (fps/fes related) tyrosine kinase; GHR, growth hormone receptor; HMGCR, 3-hydroxy-3-methylglutaryl-CoA reductase; KIF2A, kinesin heavy chain member 2A; NARS, asparaginyl-tRNA synthetase; NFIB, nuclear factor I/B; NTRK2, neurotrophic tyrosine kinase receptor, type 2; RNF20, ring finger protein 20, E3 ubiquitin protein ligase; RPS6, ribosomal protein S6; SPIN, spindlin; TMOD, tropomodulin 1; VCP, valosin containing protein.bThe number in parenthesis indicates the number of identical bases/the number of bases in the overlapped region between cDNA fragments of two species.cThe nucleotide sequences were obtained from Tsuda et al. [27].dThe nucleotide sequence was obtained from Ishijima et al. [18].
