Asrij/OCIAD1 is an endosomal protein that dose-dependently modulates JAK/STAT signaling to maintain stem cell pluripotency; STAT3 colocalizes with Asrij in endosomes and interacts with it biochemically, suggesting Asrij provides an endosomal scaffold for STAT3 activation. |

OCIAD1 overexpression in ovarian cancer cells increases LPA-induced cell adhesion to collagen I and laminin 10/11, and this effect is not blocked by PKC or PI3K inhibitors, indicating OCIAD1 promotes cell adhesion through a PKC/PI3K-independent mechanism. |

LPA induces OCIAD1 serine phosphorylation within 2 hours and upregulates OCIAD1 expression via the MKK6/p38 MAPK pathway; OCIAD1 knockdown inhibits LPA-induced adhesion to collagen I and laminin 10/11 and specifically to alpha2, alpha5, alphaV, and beta1 integrins; proteomic studies show OCIAD1 is physically associated with alpha-actin 4 and beta-actin, indicating a role in cytoskeletal regulation. |

The ARF1-Asrij endosomal axis regulates the cellular immune response by controlling crystal cell melanization and phenoloxidase activity, and suppresses Toll pathway anti-microbial peptides by regulating ubiquitination of the Toll inhibitor Cactus; Asrij (but not ARF1) is required for Imd pathway AMP production. |

OCIAD1 is an inner mitochondrial membrane protein that forms a complex with supramolecular prohibitin assemblies and is required for normal steady-state levels of mitochondrial Complex III and for proteolytic processing of the catalytic subunit cytochrome c (CYC1) by the IMMP2L protease; in OCIAD1-depleted mitochondria, unprocessed CYC1 is hemylated and incorporated into Complex III. |
