Human SEC10 (hSec10p) was identified as the human homologue of yeast Sec10p, a component of the exocyst complex. Co-transfection and immunofluorescence showed that hSec10p and mammalian Sec8p have identical subcellular distribution including peripheral cytoplasm localization, consistent with hSec10p being part of the mammalian exocyst complex involved in post-Golgi traffic. |

Yeast Sec10p has two functional domains: an N-terminal two-thirds that directly interacts with Sec15p (another exocyst component), whose overexpression displaces Sec10p from the exocyst and blocks exocytosis causing vesicle accumulation; and a C-terminal domain that does not interact with other exocyst components but is required for cell morphogenesis (reorientation of secretory pathway during cell cycle). |

Drosophila Sec10 (dSec10) is essential for endocrine (steroid hormone) secretion from the ring gland but is not required for neurotransmission, polarized secretion in nervous system, musculature, gut, or epidermis. Developmental arrest from dSec10 RNAi was partially rescued by feeding ecdysone, placing dSec10 upstream of steroid hormone secretion. |

Exocyst component Sec10 regulates primary ciliogenesis in renal epithelial cells: shRNA knockdown of Sec10 in MDCK cells results in cilia containing only basal bodies (no axoneme), while overexpression increases ciliogenesis. Sec10 knockdown prevents cyst morphogenesis in collagen matrix, overexpression increases cystogenesis. Par3 co-localizes and co-immunoprecipitates with the exocyst, suggesting the exocyst targets vesicles carrying proteins necessary for primary ciliogenesis. |

Sec10 biochemically interacts with the ciliary proteins polycystin-2 (PKD2), IFT88, and IFT20, and co-localizes with polycystin-2 at the primary cilium. Sec10 knockdown in zebrafish phenocopies polycystin-2 knockdown (curly tail, left-right patterning defects, glomerular expansion, MAPK activation), and synergistic genetic interaction between sec10 and pkd2 morpholinos supports a model where the exocyst is required for ciliary localization of polycystin-2. |

Sec10 overexpression in renal tubule cells activates the MAPK pathway (elevated basal ERK phosphorylation), which protects epithelial barrier integrity and accelerates recovery following oxidative stress. MAPK inhibitor U0126 blocked the protective effect of Sec10 overexpression, placing Sec10 upstream of ERK in this pathway. |

Sec10 interacts with the ER translocon subunit Sec61β via GST pulldown, and the exocyst is preferentially recruited to ER membranes during basolateral protein (VSV-G) translation compared to apical protein (hemagglutinin) translation in cell-free assays. Sec10 overexpression increases Sec61β phosphorylation, suggesting a regulatory role for the exocyst in basolateral protein translation/translocation. |

SEC-10 (C. elegans ortholog) operates at an intermediate step between early endosomes and recycling endosomes, forming an endosomal tubular network required for basolateral recycling of clathrin-independent endocytic (CIE) cargoes. SEC-10 coordinates with RAB-10 and microtubules to maintain endosomal tubule structure; depletion converts tubules to ring-like structures. |

Sec10 knockdown MDCK cells show abnormal mitotic spindle angles (planar cell polarity defect) and increased basal apoptotic cell extrusion; primary cilia assembly is disrupted in both Sec10 KD cysts and kidney-specific Sec10 KO mouse renal tubules. Restoring Sec10 with shRNA-resistant human Sec10 reverses these phenotypes, confirming specificity. |

Sec10 downregulation in MDCK cells accelerates wound healing and ruffle formation by reducing DGK-gamma at the leading edge. Sec10 overexpression inhibits cell migration by increasing DGKγ at the leading edge; a DGK inhibitor reverses this inhibition, placing Sec10 upstream of DGKγ in the regulation of cell migration. |

Oocyte-specific deletion of Exoc5 (Zp3-Exoc5-cKO) blocks folliculogenesis past the secondary follicle stage in adult waves (subsequent waves undergo apoptosis at preantral stage), while first-wave folliculogenesis proceeds to antral stage but produces developmentally incompetent oocytes. This demonstrates EXOC5 is required for follicular development and oocyte developmental competence. |
