Biallelic human SHARPIN loss of function induces autoinflammation and immunodeficiency
The linear ubiquitin assembly complex (LUBAC) consists of HOIP, HOIL-1 and SHARPIN and is essential for proper immune responses. Individuals with HOIP and HOIL-1 deficiencies present with severe immunodeficien...

Immunodeficiency, autoinflammation and amylopectinosis in humans with inherited HOIL-1 and LUBAC deficiency
The linear ubiquitination complex (LUBAC) is poorly understood in humans. Casanova and colleagues identify natural mutations in a component of human LUBAC and use this to dissect its function in vivo and in vitro
