hinge region

hinge re·gion

1. that part of a tRNA structure that is deformed, bending a "cloverleaf" (two-dimensional) model to form an "L" model (crystal form, as seen by electron microscopy);
2. in an immunoglobulin, a short sequence of amino acids that lies between two longer sequences and allows the latter to bend about the former.

hinge region

The part of the immunoglobulin (antibody) molecule between the Fab and Fc regions that allows flexibility.

hinge region

a proline-rich portion of an immunoglobulin heavy chain between the Fc and Fab regions that confers mobility on the two Fab arms of the antibody molecule thereby allowing it to combine better with the two epitopes.
