ETIMOLOGI PERKATAAN SPECTRIN
From spectr(e) + -in, referring to the ghosts (isolated cell membranes) of red blood cells, the source of the first known member of the class.
APAKAH MAKSUD SPECTRIN dalam CORSICA?
Spektrum
Spektrin adalah protein sitoskeletal yang melambangkan sisi intraselular membran plasma dalam sel eukariotik. Protein ini dinamakan spectrin kerana ia pertama kali diisolasi sebagai komponen utama protein sel darah merah manusia yang telah dirawat dengan detergen ringan; detergen mencairkan sel-sel dan hemoglobin dan komponen sitoplasmik lain dibasuh. Dalam mikroskop cahaya, bentuk asas sel darah merah masih boleh dilihat sebagai spectrin yang mengandungi sitoskeleton submembranous yang mengekalkan bentuk sel dalam garis besar. Ini dikenali sebagai sel darah merah "hantu", dan oleh itu protein utama hantu dinamakan spectrin. Spectrin membentuk susunan pentagonal atau heksagon, membentuk perancah dan memainkan peranan penting dalam penyelenggaraan integriti membran plasma dan struktur sitoskeletal. Pengaturan heksagon dibentuk oleh tetramer subunit spectrin yang mengaitkan filamen aktin pendek pada kedua-dua hujung tetramer. Filamen actin pendek ini bertindak sebagai kompleks fungsional yang membolehkan pembentukan mesh heksagon.
Definisi spectrin dalam kamus Corsica

Molecular Biology of Membrane Transport Disorders
The interactions of protein 4.1 with actin and spectrin are also regulated by Ca2+-

Spectrin I is composed oftwo large subunits of approximately 280 (α) and 246
kDa (β). The simplest form of spectrin is an antiparallel αβ heterodimer; however,
on the cytoplasmic surface ofthe erythrocyte membrane, it is an (αβ)2 tetramer, ...
