transporters. i worked up from gap junctions to the “Tetraspan Junctional Complex Protein (4JC) Superfamily” then after 1/2 hour confused why these diagrams of other cellular connections looked similar but had different names did it finally click in : “what are they superfamilies of” transport proteins. https://en.m.wikipedia.org/wiki/Membrane_transport_protein

TOOL: tRNA they call it an “adapter” A transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length, that serves as the physical link between the mRNA and the amino acid sequence of proteins. Transfer RNA does this by carrying an amino acid to the protein synthetic machinery of a cell called the ribosome.

DOMAIN in genetics: “A specific physical region or amino acid sequence in a protein which is associated with a particular function or corresponding segment of DNA.” Good. More backup that my principle (of principles of domains) can 1) be sequences (here of amino acids but musical notes for a melody, or list of rules or axioms) 2) be a specific physical region 3) can be associated with a function (principle and applied – that is, testable)
