Human NDR2 is excluded from the nucleus and exhibits a punctate cytoplasmic distribution, distinct from NDR1's nuclear localization. NDR2 forms stable complexes with human Mob2 (homologous to S. cerevisiae Mob1/Mob2), and this association dramatically stimulates NDR2 catalytic activity. |

NDR2 is activated by multi-site phosphorylation: Ser-282 is autophosphorylated in vivo (activation segment), while Thr-442 (hydrophobic motif) is targeted by an upstream kinase. S100B, an EF-hand Ca2+-binding protein, stimulates NDR2 autophosphorylation in vitro. NDR2 exhibits predominantly cytoplasmic localization. |

NDR2 directly phosphorylates ARK5 at conserved Thr-211 on its activation T-loop during IGF-1 signaling, thereby activating ARK5 to promote cell survival and invasion. NDR2 activation itself requires phosphorylation at Thr-75 (S100B binding, Ca2+- and PLC-γ-dependent), Ser-282 (autophosphorylation, most critical), and Thr-442 (PDK-1 dependent). |

NDR2 phosphorylates Rabin8 (a Rab8 GEF) at Ser-272, which switches Rabin8's binding specificity from phosphatidylserine (on pericentrosomal vesicles) to Sec15 (exocyst component), promoting Rab8 activation and ciliary membrane formation. Loss of this phosphorylation impairs preciliary membrane assembly and ciliogenesis. |

NDR2 localizes to peroxisomes via a C-terminal PTS1-like sequence (Gly-Lys-Leu), binds the PTS1 receptor Pex5p, and is exposed on the cytosolic surface of peroxisomes. This peroxisomal localization is required for NDR2's function in promoting primary cilium formation, as an NDR2 mutant lacking the C-terminal Leu (NDR2-ΔL) fails to rescue ciliogenesis after NDR2 knockdown. |

TRIM27 catalyzes non-degradative K6- and K11-linked ubiquitination of STK38L/NDR2 during starvation-induced autophagy. This ubiquitination activates STK38L, which then phosphorylates ULK1 at Ser495, rendering ULK1 permissive for TRIM27-mediated K48-linked hyper-ubiquitination and degradation of ULK1, thereby restraining autophagy amplitude. |

NDR2 phosphorylates Rabin8 at S272 at the trans-Golgi/Golgi exit sites (GESs), where NDR2 co-localizes with Rabin8 and the RTC-associated R-SNARE VAMP7. Phospho-mimetic Rabin8-S272E integrates into rhodopsin transport carriers (RTCs) and supports Rab8 GEF activity for ciliary trafficking; non-phosphorylatable S272A causes GES enlargement and impairs rhodopsin Golgi-to-cilia trafficking. |

STK38L (NDR2) inhibits the Hippo pathway by competitively binding to MOB1 and disrupting the LATS-MOB1 complex, in a manner independent of STK38L kinase activity. This mechanism is conserved in Drosophila, where the ortholog Tricornered similarly impairs Warts-Mats complex formation. STK38L is required for ovarian tumor growth, and its amplification correlates with YAP activation. |

NDR2 deficiency in hippocampal neurons reduces phosphorylated β1-integrin (Thr788/789) at synaptic sites, leading to decreased synaptic density and reduced long-term potentiation (LTP) in CA1; this LTP deficit can be rescued by RGD peptide-mediated integrin activation, suggesting NDR2 regulates synapse formation and plasticity via integrin-dependent mechanisms. |
