L1.2, the zebrafish paralog of L1.1 and ortholog of the mammalian cell adhesion molecule L1 contributes to spinal cord regeneration in adult zebrafish. Chen T, Yu Y, Hu C, Schachner M. PURPOSE: The aim of the study was to investigate the functional role of L1.2, the zebrafish paralog of L1.1 and ortholog of mammalian L1CAM in adult zebrafish spinal cord regeneration after injury.
AbstractOrthologs and paralogs are two fundamentally different types of homologous genes that evolved, respectively, by vertical descent from a single ancestral gene and by duplication. Orthology and paralogy are key concepts of evolutionary genomics.

2009-12-24 · “同源”包含两种情况，一是物种间的同源（ ortholog ）；另一种是同一物种内由于基因复制、分离导致的同源（ paralog ）。 2. Ortholog : Orthologs are genes in different species that have evolved from a common ancestral gene via speciation (1). Orthologous genes diverged after a speciation event, while paralogous genes diverge from one another within a species. Put another way, the terms orthologous and paralogous describe the relationships between genetic sequence divergence and … Orthologous are homologous genes where a gene diverges after a speciation event, but the gene and its main function are conserved. If a gene is duplicated in a species, the resulting duplicated genes are paralogs of each other, even though over time they might become different in … 2021-4-1 · Orthologs are genes in different species evolved from a common ancestral gene. Paralogs are gene copies created by a duplication event within the same genome.
2020-03-17 · Paralog vs. ortholog conservation. In total, we analyzed 4,869,838 residue positions in the genes within paralog families; 564,758 (12%) were only paralog and 411,284 (8%) only ortholog conserved; 3,393,797 (80%) positions were either conserved or not-conserved in both.

A1x and A2y are paralogously related as are A2x and A1y. homolog, ortholog, paralog, pseudoortholog, pseudoparalog, xenolog Abstract Orthologs and paralogs are two fundamentally different types of ho-mologous genes that evolved, respectively, by vertical descent from a single ancestral gene and by duplication. Orthology and paral-ogy are key concepts of evolutionary genomics. A clear distinction 2006-06-01 · Additionally, species-specific expansions (paralog groups that exist only in one organism) are provided.
av H Yang · 2018 · Citerat av 19 — We also developed new orthologs to facilitate cross-species comparisons. Extending the Drosophila orthology to include ncRNAs should allow for the Lyer V, Richter J, Wiel C, Bayraktaroglu L, Birney E, Crosby MA, et al.
2001-02-08 · Yet another misuse of the terms 'ortholog' and 'paralog' is quite common in the literature as seen, for example, in a review in Genome Biology by Gerlt and Babbitt . Here, orthologs are defined as homologs in different species that catalyze the same reaction, and paralogs are defined as homologs in the same species that do not catalyze the same reaction. Homologs, Orthologs, and Paralogs - these 3 terms are conceptually related.
Paralog. Definition. Paralogous genes (or paralogs) are a particular class of homologous genes. They are the result of gene duplication and the gene copies resulting from the duplication are called paralogous of each other.

A paralog labelled as a gene_split is an artefactual type of paralogy. It is commonly realted to fragmented genome assemblies or a gene prediction that is poor in supporting evidences (cDNA, ESTs, proteins, etc.). For orthologs this is the speciation event. For in-paralogs this is the duplication event. Accordingly you would expect a situation in which pradoxically a protein and it's paralog would be more similar than that protein and its ortholog in another species.
So, this is the key difference between orthologous and paralogous genes. Orthologs are genes in different species evolved from a common ancestral gene. Paralogs are gene copies created by a duplication event within the same genome. While orthologous genes kept the same function, paralogous genes often develop different functions due to missing selective pressure on one copy of the duplicated gene.

The two lines show a dramatic difference in appetite (hyperphagia vs. anorexia) which hampers accurate reconstruction of closely related gene paralogs, either findings are translated to aid human patients with orthologous disease sets.
Orthologs are corresponding genes in different lineages and are a result of speciation, whereas paralogs result from a gene duplication.
