Gene
RTKN, RTKN1
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Mediates Rho signaling to activate NF-kappa-B and may confer increased resistance to apoptosis to cells in gastric tumorigenesis. May play a novel role in the organization of septin structures.3 Publications

Tissue specificityi

Highly expressed in prostate, moderately in kidney, heart, brain, spleen, testis, placenta, small intestine, pancreas, skeletal muscle and peripheral blood leukocytes, and weakly in ovary, colon and thymus. Weakly expressed in all normal cell lines tested. Overexpressed in various cancer cell lines.2 Publications

Interactioni

Subunit structurei

Interacts via its C-terminal region with the TAX1BP3 PDZ domain. This interaction facilitates Rho-mediated activation of the c-Fos serum response element (SRE). Interacts with SEPT9. Specifically binds to GTP-bound RHOA, RHOB and RHOC and inhibits their GTPase activity.By similarity2 Publications
