Abstract

The Suppressors of Cytokine Signalling (SOCS) are a family of proteins that are produced in response to signals from a diverse range of cytokines and growth factors and which act to attenuate cytokine signal transduction. Members of the SOCS family form a classical negative feedback loop with key actions involving inhibition of the Janus Kinase-Signal Transducers and Activators of Transcription (JAK-STAT) signalling cascade. Extensive analyses have implicated each of CIS, SOCS1, SOCS2 and SOCS3 in the regulation of Growth Hormone (GH) signal transduction. The expression of each of these SOCS proteins is induced in cells stimulated with GH and their over-expression in cell lines blocks aspect..
