Aurora kinase A binds PHLDA1 (TDAG51) and the two proteins co-localize in the cytosol (Johnson et al. 2011). Although phosphorylation of AURKA at threonine residue T288 within the catalytic loop of AURKA is needed for AURKA kinase activity (Walter et al. 2000), AURKA phosphorylation has not been specifically examined in the context of AURKA interaction with PHLDA1 and AURKA is therefore shown as unphosphorylated.
