CHICA (FAM83D) localizes to the mitotic spindle, is upregulated and phosphorylated during mitosis, and is required for proper metaphase plate organization and polar ejection forces. CHICA co-immunoprecipitates with the chromokinesin Kid and is required for Kid's spindle localization (but not its chromosome association). Depletion of CHICA or Kid (or both) causes chromosomes to collapse onto poles of monastrol-induced monopolar spindles. |

The LC8 dynein light chain binds to a 69-residue intrinsically disordered region of CHICA (FAM83D) that contains four tandem TQT motifs. Crystal structures show that the first TQT motif dominates LC8 recruitment with rigidly fixed TQT-LC8 contacts, while non-TQT interactions are flexible. This defines an 'anchored flexibility' model for LC8 motif recognition. |

FAM83D recruits CK1α to the mitotic spindle. Cells lacking FAM83D, or bearing CK1α-binding-deficient FAM83D(F283A) knockin mutations, display pronounced spindle positioning defects and prolonged mitosis. Restoring FAM83D at the endogenous locus or artificially delivering CK1α to the spindle rescues these defects, establishing FAM83D as the spindle-targeting adaptor for CK1α during mitosis. |

FAM83D knockdown in colorectal cancer cells upregulates FBXW7 protein and reduces Notch1 protein. FBXW7 siRNA reverses suppression of Notch1 by FAM83D knockdown, and Notch1 overexpression reverses the anti-proliferative and anti-migratory effects of FAM83D knockdown, placing FAM83D upstream of the FBXW7/Notch1 axis. |

In skeletal muscle cells, Fam83d overexpression represses myosin heavy chain and myogenin expression and suppresses phosphorylated ERK and AKT. The putative PLD-like domain of Fam83d is required for destabilizing CK1α and inhibiting ERK phosphorylation. Fam83d is induced during neurogenic muscle atrophy and localizes in a punctate cytoplasmic pattern in C2C12 cells. |

HMMR binds to the C-terminal α-helix of SACK1D/FAM83D, co-localizes with the SACK1D-CK1α complex throughout mitosis, and is required for SACK1D-CK1α complex formation at the spindle and for correct spindle alignment. HMMR binding stabilizes SACK1D. Mitotic hyperphosphorylation of SACK1D signals its destruction upon mitotic exit, a process that also requires the C-terminal α-helix, suggesting hyperphosphorylation exposes a C-terminal degron. |

Knockdown of FAM83D in glioma causes abnormal cell division leading to accumulation of cytoplasmic double-stranded DNA, which activates the cGAS-STING signaling pathway to induce tumor cell senescence. FAM83D-depleted cells also produce a SASP that promotes senescence in neighboring cells and drives macrophage polarization toward an M1 state via ANXA1-FPR1/2 ligand-receptor signaling. |
