Top: An ancestral gene duplication produces two paralogs (histone H1.1 and 1.2). A speciation event produces orthologs in the two daughter species (human and chimpanzee). Bottom: in a separate species , a gene has a similar function (histone-like nucleoid-structuring protein) but has a separate evolutionary origin and so is an analog.
The term "ortholog" was coined in 1970 by the molecular evolutionist Walter Fitch. [41] Homologous sequences are paralogous if they were created by a duplication event within the genome. For gene duplication events, if a gene in an organism is duplicated, the two copies are paralogous. They can shape the structure of whole genomes and thus ...

The paralogs of EVA1C are EVA1A (Eva-1 Homolog A) and EVA1B (Eva-1 Homolog B). [17] [18] The thorny skate (Amblyraja radiata) was found to be the most distant ortholog in EVA1A, EVA1B, and EVA1C. [14] [19] [20] The divergence time of humans and the thorny skate is 464 million years ago. [16]
In Hyphomicrobiales and Enterobacteriales, syntenic genes encode a large number of essential cell functions and represent a high level of functional relationships. [ 15 ] Patterns of shared synteny or synteny breaks can also be used as characters to infer the phylogenetic relationships among several species, and even to infer the genome ...
And then it calculates the statistical significance of each match. Cutoffs are made per position and Ks values are set to prevent false "orthologs" from being grouped together. “Paralogs” are identified by finding sequences that are closer within species than other species. This resource ceased making updates in 2014. [2]

Double-stranded RNA-binding protein Staufen homolog 1 is a protein that in humans is encoded by the STAU1 gene. [5] [6] [7]Staufen is a member of the family of double-stranded RNA (dsRNA)-binding proteins involved in the transport and/or localization of mRNAs to different subcellular compartments and/or organelles.
