COT Antibody – Rabbit Polyclonal

This gene is an oncogene that encodes a member of the serine/threonine protein kinase family. The encoded protein localizes to the cytoplasm and can activate both the MAP kinase and JNK kinase pathways. This protein was shown to activate IkappaB kinases, and thus induce the nuclear production of NF-kappaB. This protein was also found to promote the production of TNF-alpha and IL-2 during T lymphocyte activation. This gene may also utilize a downstream in-frame translation start codon, and thus produce an isoform containing a shorter N-terminus. The shorter isoform has been shown to display weaker transforming activity. Alternate splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Sep 2011]

Cot: an oncogenic Ser/Thr kinase of the STE group. Activates IkappaB kinases, thus inducing the nuclear translocation of NF-kappaB. Promotes the production of TNF-alpha and IL-2 during T lymphocyte activation. Interacts with NFkB-p105. Overexpressed and amplified in breast tumors. Viral insertions induce rat lymphomas and mouse mammary carcinomas. Isolated as a transforming factor in two cell lines. Mediates LPS activation of macrophages. 2 isoforms of the human protein are produced by alternative initiation.
