Origin: Formed within English, by derivation. Etymons: ribosome n., -phore comb. form, -in suffix¹.

Etymology: < ribo- (in ribosome n.) + -phore comb. form + -in suffix¹.

Biochemistry.

Any of a number of membrane proteins involved in binding ribosomes to the rough endoplasmic reticulum during protein synthesis.

1977 Jrnl. Cell Biol. 75 ii. 234a These proteins, which were designated ribophorin I and II (65,000 and 63,000 daltons, respectively) are present in a fixed stoichiometric ratio with respect to the ribosomes.

1984 E. Holtzman & A. B. Novikoff Cells & Organelles (ed. 3) ii. iv. 146 According to one hypothesis, two of the proteins (‘ribophorins’) serve as receptor sites that help to bind the ribosomes.
