Too much can make you fat, as it is calorific. Also, too little can make you fat in a round about way so yes it can help weight loss...
Muscle mass burns a lot of calories even at rest, so it is good for fat loss to build some muscle (which requires enough protein in your diet).
If you're very low on protein you can actally lose muscle as its amino acids are stripped for use in the immune system and for general repairs etc. This will reduce your metabolism and more of your food could be stored as fat.
