1970 Biol. Bull. 139 438 The protein represents..less than 1% of the total flagellar protein... The term ‘nexin’ is proposed for this protein, derived from the Latin nexus, a tie binding together members of a group.
1984 E. Holtzman & A. B. Novikoff Cells & Organelles (ed. 3) ii. ii. 253 (caption) The fine links, made of the protein ‘nexin’, attaching adjacent doublets to one another, can be extensively stretched without breaking.
1996 New Scientist 14 Sept. 44/2 Each microtubule is made up of tubulin molecules, stacked into rods which are joined together by dynein motor proteins and nexin linker proteins.
