Gene Information

human ... TIAM1(7074)

General description

T-lymphoma invasion and metastasis-inducing protein 1 (UniProt Q13009; also known as TIAM-1) is encoded by the TIAM1 gene (Gene ID 7074) in human. TIAM-1 is a ubiquitously expressed guanine nucleotide exchange factor (GEF) that specifically activates the Rho-like GTPase Rac1 in response to growth factors and cell-substrate interaction. TIAM-1 associates with GTP-bound Ras and functions as an effector that mediates Rac activation by Ras. TIAM-1 promotes the formation of adherens junctions and the induction of an epithelial-like phenotype in mesenchymal cells, and is essential for the formation and maintenance of cadherin-based adhesions. Tiam1-knockdown in mice protects against Ras-induced skin carcinogenesis as a result of increased apoptosis and reduced proliferation/growth of keratinocytes. However, the fewer skin tumors developed progress more frequently to malignancy in Tiam1-knockout mice, indicating that loss of Tiam1 stimulates malignant conversion. Cellular TIAM-1 is targeted for proteasome-dependent degradation by the SCFbTrCP ubiquitin ligase in cooperation with casein kinase 1 and the MEK/ERK pathway upon mitogenic stimulation.

Specificity

This rabbit polyclonal antibody targets a C-terminal region of human and mouse TIAM-1 sequences reported by UniProt (Q13009 and Q60610).

Immunogen

KLH-conjugated linear peptide corresponding to a C-terminal region sequence of human TIAM-1.

Application

Anti-TIAM-1 Antibody, Cat. No. ABN1488, is a highly specific rabbit polyclonal antibody, that targets TIAM-1 and has been tested in Western Blotting.

Receptor tyrosine kinases (RTKs) are often overexpressed or mutated in cancers and drive tumor growth and metastasis. In the current model of RTK signaling, including that of MET, downstream phosphatidylinositol 3-kinase (PI3K) mediates both cell proliferation and cell migration, whereas
