اسفنگوزین کیناز ۲ (انگلیسی : Sphingosine kinase 2 ) یک پروتئین است که در انسان توسط ژن «SPHK2 » کُدگذاری میشود.[ ۴]
این پروتئین، واکنشِ فسفریلاسیون و تبدیل اسفنگوزین به اسفنگوزین-۱-فسفات را میانجیگری و تسهیل میکند. محصول حاصله در بسیاری از فرایندهای مهم سلولی همچون کوچ یاخته ، خزان یاختهای ، رشد یاخته و در ایجاد سرطان از طریق ایجاد تومور و رگزایی دخالت دارد.
