Paralogous genes often have different functions and, therefore, less sequence similarity than orthologs. As for acquiring novel functions without duplication, believe me I know, I have spent the last couple of years working on moonlighting proteins :). $\endgroup$ – terdon Oct 19 '12 at 18:45

One of the specific issues relevant to genome evolution through rearrangement is evolution of multiple homologous genes present in a genome, often called paralogous genes. The homeobox gene family plays a pivotal role in regulating patterning and axial morphogenesis in vertebrates.

The ribosomal small subunit (SSU) rRNA gene has emerged as an important genetic marker for taxonomic The SSU genes in the core genome, mitochondria and chloroplast are conceptually paralogous and should in most situations not be 

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 to occupy two different positions in the same genome, then the two copies are paralogous.

Paralogous genes

Using genomic location and coalescent simulation to investigate gene tree discordance in which may result in unwarranted comparisons of paralogous genes.

Los genes ortólogos y parálogos son dos tipos de genes homólogos, es decir, genes que surgen de una secuencia ancestral de ADN común. Los genes ortólogos divergieron después de un evento de especiación, mientras que los genes paralogos divergen entre sí dentro de una especie. Dicho de otra forma, los términos ortólogo y paralogous describen … Paralogous Gene Synonyms. Definition. Paralogous genes (or paralogs) are a particular class of homologousgenes. They are the result of gene Abstract Orthologs 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.

Paralogous genes

They have evolved due to a mutation that occurred in the genetic duplication process. Therefore, they are present within the same genome. Paralogous genes may carry out different functions.

Wilson 3 Nutrient acquisition is a central challenge for all organisms. For the fungal pathogen Candida albicans, utilization of amino acids has been shown to be critical for survival, immune evasion, and escape, while the importance of catabolism of host-derived proteins and peptides in vivo is less well understood. Stp1 and Stp2 are paralogous transcription factors (TFs) regulated by the Ssy1-Ptr3 Lastly, paralogous duplicate genes may be retained in evolution to allow more control of gene dosage [25, 26].
