Human angiogenin diverged from ribonuclease, for example, and while the two paralogs remain similar in tertiary structure, their functions within the cell are now quite different. [ citation needed ] It is often asserted that orthologs are more functionally similar than paralogs of similar divergence, but several papers have challenged this notion.
Pierre Belon systematically compared the skeletons of birds and humans in his Book of Birds (1555) [1]. Homology was noticed by Aristotle (c. 350 BC), [1] and was explicitly analysed by Pierre Belon in his 1555 Book of Birds, where he systematically compared the skeletons of birds and humans.
Some basic conventions, such as (1) that animal/human homolog (ortholog) pairs differ in letter case (title case and all caps, respectively) and (2) that the symbol is italicized when referring to the gene but nonitalic when referring to the protein, are often not followed by contributors to medical journals.
The yeast homolog of Drp1 is dynamin-1 (Dnm1), which interacts with Fis1 through Mdv1. This interaction causes Dnm1 to oligomerize and form rings around dividing mitochondria at the so-called "constriction point". [8] [16] Drp1 has also been shown to interact with GSK3B. [6] In mammals, Drp1 receptors include Mff, Mid49 and Mid51 [17] [18]

Homology (anthropology), analogy between human beliefs, practices or artifacts owing to genetic or historical connections; Homology (psychology), behavioral characteristics that have common origins in either evolution or development
Orthology (biology) - homologous sequences originate from the same ancestors (homolog e.g. all globin protein), which are separated from each other after a speciation event, e.g. human beta and chimp beta globin. An orthologous gene is a gene in different species that evolved from a common ancestor by speciation.
Notch homolog 2 N-terminal-like is a family of proteins that in humans consists of 3 proteins (NOTCH2NLA, NOTCH2NLB, and NOTCH2NLC) and is encoded by NOTCH2NL gene. It appears to play a key role in the development of the prefrontal cortex, a part of the brain.
