A typical 1 oz serving of pine nuts contains 3.8 grams of protein (13.7 g per 100 g), which makes it a moderate source of protein. That covers roughly 8% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 8% of the calories in pine nuts come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Among the 31 nuts in the database, pine nuts ranks 18th by protein per serving, and 554th out of all 796 foods on the site. Set against roasted cashews, another nut entry in the database, a serving carries about 0.5 g less protein (roasted cashews has 4.3 g per 1 oz).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by weight at 28 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
