Protein Tob1 is a protein that in humans is encoded by the TOB1 gene.[1][2][3]

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 suppresses cell growth in tissue culture. The protein undergoes phosphorylation 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.[3]

Interactions

TOB1 has been shown to interact with MARCKS,[4] RPS6KA1,[5] CNOT7,[6][7] MAPK1[8] and Mitogen-activated protein kinase 9.[8]
