In breast cancer or prostate cancer, Notchseems to act as an oncogene,[sup][15] while in bladder cancer it possesses characteristics as a tumor suppressor gene.[sup][16] Moreover, it may act as both oncogene and tumor suppressor gene in prostate cancer simultaneously.[sup][17] An important role for Notch signaling in thyroid cancer has been well documented and the members of Notch signaling are abnormally expressed in thyroid cancer.[sup][18],[19] NRARP encodes a small evolutionarily conserved protein containing two ankyrin repeats which is a component of a negative feedback system to attenuate Notch pathway-mediated signaling.

Background: The Notch-regulated ankyrin repeat protein (NRARP) is recently found to promote proliferation of breast cancer cells.

The first, the potential phosphorylated domain, located between the ankyrin repeats and the proline, glutamic acid, serine, and threonine-rich domain, can enhance binding of the NICD to RBP-J[kappa].

Role of Notch signaling in the mammalian heart

There are indications that mechanisms underpinning host-microbe interactions are encoded on the genome of "Candidatus Poribacteria WGA A3." These are proteins with eukaryote-like domains, such as ankyrin repeats and tetratricopeptide repeats (TPR), which are likely to mediate protein-protein interactions (Siegl et al., 2011).
