DNA/RNA

Description

Size: 3300 bases.

Transcription

2 introns. Transcription generates 3 different mRNAs, 2 spliced variants and 1 unspliced form.

Proteins

Atlas Image
KIR = kinase inhibitory region.

Description

225 amino acids, 24770 Da.

Expression

Widely expressed in normal and tumor tissues. Expression in tumors is variable due to its different functions.

Localisation

Cytoplasm.

Function

SOCS is a negative regulator of cytokines that signal through the JAK/STAT pathway. It binds to tyrosine kinase receptors such as gp130 subunit of receptors. It interacts with cytokine receptors or JAK kinases and interaction with growth factor receptors (insulin-like growth factor-I, insulin, fibroblast growth factor). It inhibits JAK2 kinase activity. Part of the ubiquitin-protein ligase complex which contains elongin, RNF7, and CUL5. Binding to leptin. Tumor promoting or tumor suppressive functions. Antagonizing cAMP-antiproliferative effects. SOCS3 suppresses erythropoietin in fetal liver and IL-6 signaling in vivo.

Mutations

Mutations not detected.

Implicated in

Entity name
Lung cancer
Note
SOCS-3 acts as a tumor suppressor and is frequently lost in the disease. Its transient transfection in lung cancer cell lines leads to a decrease in proliferation.
Entity name
Liver cancer
Note
SOCS-3 is silenced by methylation. SOCS-3 is a tumor suppressor in this malignancy. It is implicated in regulation of migration of cancer cells. SOCS-3 deletion enhances JAK/STAT and FAK signaling.
Entity name
Barrets adenocarcinoma
Note
SOCS-3 is methylated. It is considered as a tumor suppressor.
Entity name
Glioblastoma multiforme
Note
SOCS-3 expression is lost through promoter methylation.
Entity name
Head and neck squamous cell cancer
Note
SOCS-3 is frequently down-regulated as a result of promoter methylation. It causes a growth inhibition.
Entity name
Hematological malignancies
Note
SOCS-3 inhibits megakaryocytic growth, overexpression of SOCS-3 is associated with a decreased survival of patients with follicular lymphoma.
Entity name
Melanoma
Note
SOCS-3 is a tumor promoter in melanoma and is constitutively expressed in several cell lines.
Entity name
Prostate cancer
Note
SOCS-3 stimulates proliferation and inhibits apoptosis in prostate cancer cells which do not express the androgen receptor. It may also antagonize the effects of fibroblasts growth factor and mitogen-activated protein kinases. In androgen-sensitive prostate cancer cells, SOCS-3 is induced by androgen and may inhibit androgen-stimulated proliferation and secretion.
Entity name
Diabetes
Note
SOCS-3 may antagonize function of insulin-like growth factors.
Entity name
Various cancers
Prognosis
Loss of protein expression and promoter hypermethylation occur in lung, liver cancer, head and neck squamous cell cancer. Overexpression occurs in melanoma and prostate cancer.
