This gene encodes a member of the tob/btg1 family of anti-proliferative proteins that have the potential to regulate cell growth. When exogenously expressed, this protein supresses cell growth in tissue culture. The protein undergoes phophorylation by a serine/threonine kinase, 90 kDa ribosomal S6 kinase. Interactions of this protein with the v-erb-b2 erythroblastic leukemia viral oncogene homolog 2 gene product p185 interferes with growth suppression. This protein inhibits T cell proliferation and transcription of cytokines and cyclins. The protein interacts with both mothers against decapentaplegic Drosophila homolog 2 and 4 to enhance their DNA binding activity. This interaction inhibits interleukin 2 transcription in T cells.Matsuda S., Oncogene 12:705-713(1996).Ebert L., Submitted (JUN-2004) to the EMBL/GenBank/DDBJ databases.Kalnine N., Submitted (OCT-2004) to the EMBL/GenBank/DDBJ databases.

Species
Homo Sapiens (Human)
Specificity
The antibody detects endogenous levels of TOB1 only when phosphorylated at serine 164.
Anti-proliferative protein; the function is mediated by association with deadenylase subunits of the CCR4-NOT complex
Protein Families
BTG family
Tissue Specificity
Ubiquitous.
Buffer
Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.

Format
liquid
Purification
Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy usi
