LUBAC
A ubiquitin ligase complex that catalyzes linear head-to-tail polyubiquitin conjugation on its targets. In human the complex consists of RBCK1, RNF31 and SHARPIN, and has an MW of approximately 600 kDa, suggesting a heteromultimeric assembly of its s
Linear ubiquitin chain assembly complex (LUBAC) is a multi-protein complex and the only known E3 ubiquitin ligase able to conjugate ubiquitin in a head-to-tail manner to generate linear (M1-linked) polyubiquitin chains. The complex is currently known to be composed of three proteins: heme-oxidized IRP2 ubiquitin ligase 1 (HOIL-1),...
