SOCS1 (suppressor of cytokine signaling 1)
The SOCS1 functions downstream of cytokine receptors, and takes part in a negative feedback loop to attenuate cytokine signaling. The SOCS1 is rapidly induced following stimulation by several type I and type II cytokines, and it attenuates their signaling by its ability to bind and inhibit all four of the Janus family of intracellular tyrosine kinases (JAKs). The SOCS1 functions as a negative r...
متن کاملCyclin D activates the Rb tumor suppressor by mono-phosphorylation
The widely accepted model of G1 cell cycle progression proposes that cyclin D:Cdk4/6 inactivates the Rb tumor suppressor during early G1 phase by progressive multi-phosphorylation, termed hypo-phosphorylation, to release E2F transcription factors. However, this model remains unproven biochemically and the biologically active form(s) of Rb remains unknown. In this study, we find that Rb is exclu...
متن کاملSuppressor of cytokine signaling-1 (SOCS1) inhibits lymphocyte recruitment into the retina and protects SOCS1 transgenic rats and mice from ocular inflammation.
PURPOSE Suppressors of cytokine signaling (SOCS) proteins regulate the intensity and duration of cytokine signals and defective expression of SOCS1 and SOCS3 has been reported in a number of human diseases. The purpose of this study was to investigate the role of SOCS1 in intraocular inflammatory diseases (uveitis) and whether SOCS1 expression is defective in patients with ocular inflammatory d...
متن کاملHedgehog/GLI Signaling Activates Suppressor of Cytokine Signaling 1 (SOCS1) in Epidermal and Neural Tumor Cells
Sustained hedgehog (Hh) signaling mediated by the GLI transcription factors is implicated in many types of cancer. Identification of Hh/GLI target genes modulating the activity of other pathways involved in tumor development promise to open new ways for better understanding of tumor development and maintenance. Here we show that SOCS1 is a direct target of Hh/GLI signaling in human keratinocyte...
متن کاملThe tumor suppressor hTid1 inhibits STAT5b activity via functional interaction.
STAT5a and -5b (signal transducers and activators of transcription 5a and 5b) proteins play an essential role in hematopoietic cell proliferation and survival and are frequently constitutively active in hematologic neoplasms and solid tumors. Because STAT5a and STAT5b differ mainly in the carboxyl-terminal transactivation domain, we sought to identify new proteins that bind specifically to this...
