however, it is concluded that the gene is expressed ubiquitously throughout all tissue types with more expression within tissues involved in the immune system and skeletal muscle tissue. hpa rna-seq normal tissue expression from ncbi gene entry on cdv3. the expression of cdv3 generally decreases throughout fetal development, but expression levels remain high. tissue-specific circular rna induction during human fetal development from ncbi gene entry on cdv3. rna sequencing of total rna from 20 human tissues from ncbi gene entry on cdv3. illumina bodymap2 transcriptome from ncbi gene entry on cdv3. protein level regulation a conceptual translation was made from ncbi reference sequence nm_017548.4. amino acids conserved in at least 70% of vertebrate orthologous proteins are bolded (seen in the section below). a conceptual translation showing predicted sites of cdv3 protein regulation. evolution orthologs the following orthologs were found through the ncbi database. the date of divergence between species and homo sapies was determined using timetree. the sequence identity and similarity were found using blast. genus and species common name taxonomic group date of divergence (median time) accession number sequence length (aa) sequence identity sequence similar homo sapiens human mammalia 0 q9uky7 258 100 100 macaca mulatta rhesus macaque mammalia 28.1 afh33110 257 98 98 callithrix jacchus common marmoset mammalia 42.6 jab08658 257 98 98 castor canadensis american beaver mammalia 88 jav41819 265 89 89 mus musculus house mouse mammalia 89.8 q4vaa2.2 281 73 79 lonchura striata domestica society finch bird 320 owk55384 248 62 74 xenopus laevis african clawed frog amphibia 353 np_001080515 240 58 73 electrophorus electricus electric eel fish 432 xp_026860127 230 55 74 oryzias melastigma marine medaka fish 432 xp_024136300 230 50 63 danio rerio zebrafish fish 432 np_997886 236 48 59 paralogs no human paralogs were found for cdv3 genecards and geneslikeme databases through the weizmann institute of science. there were not any other relevant sources when the google search was conducted. phylogenetic tree a phylogenetic tree was developed from the species listed in the table above using "one click mode" on phylogeny.fr. phylogenetic tree of species with cdv3 orthologs using phylogeny.fr interacting proteins interacting protein sources supporting the interaction function common tissues myc intact, mentha family of regular genes and proto-oncongenes;
