Binding to beta-2-microglobulin.

Binding to a lipid antigen.

Enables the transfer of a single solute from one side of a membrane to the other by a mechanism involving conformational change, either by facilitated diffusion or in a membrane potential dependent process if the solute is charged.

Binding to an endogenous cellular lipid antigen.

Enables the facilitated diffusion of urea (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.

OBSOLETE. (Was not defined before being made obsolete).

Enables the facilitated diffusion of methylammonium (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. Methylammonium is CH3NH2.
