What is the function of this protein?
Centrosomal protein that plays a key role in cell delamination by regulating microtubule organization (By similarity).  Required for the delamination and retention of neural stem cells from the subventricular zone during neurogenesis (By similarity).  Also regulates the epithelial-to-mesenchymal transition in other epithelial cells (By similarity).  Acts by increasing centrosomal microtubule nucleation and recruiting nucleation factors and minus-end stabilizers, thereby destabilizing microtubules at the adherens junctions and mediating constriction of the apical endfoot (By similarity).  In addition, may also act as a transcription factor that specifically activates the expression of the CD40 receptor and its ligand CD40L/CD154, two cell surface molecules on lymphocytes that are critical for antigen-dependent-B-cell development (PubMed:11268217).  Binds to A/T-rich promoters (PubMed:11268217).  It is unclear how it can both act as a microtubule organizer and as a transcription factor; additional evidences are required to reconcile these two apparently contradictory functions (Probable).
What are the official names of this protein?
Microtubule organization protein AKNA, AT-hook-containing transcription factor.
What is the protein family that this protein belongs to?
Belongs to the AKNA family.
What are the subcellular locations of this protein?
Cytoplasm, cytoskeleton, microtubule organizing center, centrosome, centriole. Nucleus. Note=Localizes to the distal part of the subdistal appendages of the mother centriole in interphase. Also found at the proximal ends of centrioles and along microtubules. The centrosomal localization is dependent on centrioles. Dissociates from centrosomes during M-phase without proteolytic degradation and reassembles at the centrosomes during late telophase and early G1 phase. Dissociation and reassembly is regulated by phosphorylation.
