Suppressor of cytokine signaling 1 (SOCS1), also known as Jak-binding protein (JAB), is a negative regulator to a subset of protein-tyrosine kinases. This 211-amino acid protein has a molecular mass of about 23.5 kD. The TEC-binding region of SOCS1 resides in the N terminus. SOCS1 associates with Tec and suppresses its kinase activity.1 The SOCS1 gene is intronless and is mapped to on chromosome 16p13.13.2 SOCS1 regulates the JAK/STAT signal-transduction pathway.3 Moreover, it contributes to protection against hepatic injury and fibrosis, and may also protect against hepatocarcinogenesis.4
