box-containing (ASB) family of proteins. It consists of an ankyrin repeat sequence and a SOCS box domain. The SOCS box plays a role in connecting suppressor of cytokine signaling (SOCS) proteins and their binding partners with the elongin B and C complex, potentially facilitating their degradation. This gene is induced by all-trans
