One possibility is that they could provide the binding sites for accessory proteins.

However, there are also viral nonstructural proteins and viral regulatory and accessory proteins.

An accessory protein that helps targets the enzyme to the centrosome.

The alpha and beta appendage domains bind to accessory proteins and to clathrin.

He has recently extended these studies to obtain structural images of RNA polymerase associated with accessory proteins.

The function of these accessory proteins remains unknown.

This precursor undergoes a complex post-translational maturation process that requires a number of accessory proteins.

The enzyme requires no additional cofactors (such as ATP) or accessory proteins for its function.

When accessory proteins assemble with α subunits, the resulting complex can display altered voltage dependence and cellular localization.

A viral regulatory and accessory protein is a type of viral protein that can play an indirect role in the function of a virus.
