The protein is a metalloprotease that negatively regulates Wnt signaling by cleaving and inactivating specific Wnt proteins (WNT3A, WNT5A), and is required for proper head formation during development. TRABD2B is highly constrained against loss-of-function variants (pLI 0.84, LOEUF 0.42), but no established Mendelian diseases have been reported for this gene to date.
