spectrin
spec·trin S0618050 (spĕk′trĭn)n. A fibrous protein that links with actin filaments and is the major component of the sturdy cytoskeleton that underlies the plasma membrane of red blood cells.
[spect(e)r (so called because a red blood cell without hemoglobin is called a ghost) + -in.]spectrin (ˈspɛktrɪn) n (Biochemistry) any one of a class of fibrous proteins found in the membranes of red blood cells, the brain, the intestine, etc[C20: 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]spectrin
spectrin [spek´trin] a contractile protein attached to glycophorin at the cytoplasmic surface of the cell membrane of erythrocytes, important in maintenance of cell shape.spec·trin (spek'trin), A filamentous contractile protein that together with actin and other cytoskeleton proteins forms a network that gives the red blood cell membrane its shape and flexibility; a defect or deficiency of spectrin is associated with hereditary spherocytosis and hereditary elliptocytosis; the principal component of the membrane skeleton of red blood cells. It comprises two units, an alpha unit of MW 280,700 [MIM*182860] and a beta unit of MW 246,040 [MIM*182870].spectrin (spĕk′trĭn)n.
