Introduction The ANKRD16 gene is located on chromosome 10p15.3 and encodes a protein with multiple ankyrin repeat motifs. Ankyrin repeats are one of the most common protein-protein interaction domains in nature, found in over 400 human proteins [@mosavi2004].
Structure ANKRD16 contains:
N-terminal signal peptide : Implies possible secretionAnkyrin repeat domain (6 repeats) : The signature structural elementPotential nuclear localization signals : Suggesting nuclear functionC-terminal regulatory regions : Post-translational modification sitesAnkyrin Repeat Proteins in Neuronal Function The ankyrin repeat family includes numerous neuronal proteins:
ANK3 (Ankyrin-G) : Essential for axon initial segment formationANK2 (Ankyrin-B) : Regulates neuronal polarity and traffickingANKRD11 : Transcriptional coactivator with neurodevelopmental rolesANKRD16 may participate in similar protein interaction networks [@bennett2006].
Potential Cellular Functions
Protein Quality Control Ankyrin repeat proteins often participate in:
Ubiquitin-proteasome system interactions
