Connecting the outside-of-the-cell portion of PD-1 with the inside portion is the transmembrane segment.

From Science Daily

Study results showed that PD-1 forms a dimer through interactions of its transmembrane segment.

From Science Daily

Further immune cell testing in mice showed that encouraging PD-1 to form dimers, specifically in the transmembrane domain but not in its outer or inner regions, increased its ability to suppress T cell activity, while decreasing transmembrane dimerization lowered PD-1's ability to inhibit immune cell activity.
