BFAR

Membrane-bound E3 ubiquitin ligase that plays a role in several processes including apoptosis regulation or reticulum endoplasmic stress. Has anti-apoptotic activity, both for apoptosis triggered via death-receptors and via mitochondrial factors. Contributes to the dynamic control of IRE1/ERN1 signaling during ER stress by inducing BAX inhibitor 1/TMBIM6 proteasomal degradation. Promotes the activation of TGF-beta signaling by mediating the 'Lys-63'-linked ubiquitination of TGFBR1 which is critical to activate the pathway. Together with NGFR, negatively regulates NF-kappa-B and JNK-related signaling pathways. Promotes the proteasome-mediated degradation of PNPLA3, a protein involveld in lipid metabolism..
