This gene encodes a major histocompatibility complex, class II associated, type I transmembrane protein which belongs to the butyrophilin-like B7 family of immunoregulators. It is thought to be involved in immune surveillance, serving as a negative T-cell regulator by decreasing T-cell proliferation and cytokine release. The encoded protein contains an N-terminal signal peptide, two pairs of immunoglobulin-like domains, separated by a heptad peptide sequence, and a C-terminal transmembrane domain. Naturally occurring mutations in this gene are associated with sarcoidosis, rheumatoid arthritis, ulcerative colitis, inflammatory bowel disease, myositis, type 1 diabetes, systemic lupus erythematosus, acute coronary syndrome, and prostate cancer.

Butyrophilin-like protein 2 is a protein that in humans is encoded by the BTNL2 gene.

Because it is associated with the immune system and the major histocompatibility complex, it has been implicated in many diseases (see further reading list below). A large scale study found it to be the protein under the most stringent selection in the human genome in 8 out of 12 geographic regions using the HKA test.
