POTE ankyrin domain family, member B is a protein in humans that is encoded by the POTEB gene.(Prostate, Ovary, Testes Expressed ankyrin domain family member B).It is most likely involved in mediating protein-protein interaction via its 5 ankyrin domains. POTEB is most probably aids in intracellular signaling, but is not likely to be a secreted or nuclear protein. POTEB's function is likely to be regulated via 17 potential phosphorylation sites. There is currently no evidence to suggest that POTEB has nuclear localization signals.
