KIAA0513 is a conserved maternal protein with pleiotropic roles in developmental and disease processes. In vertebrate oogenesis, KIAA0513 (also identified as Krang in zebrafish) functions in cortical granule biology during egg activation, a critical step in the oocyte-to-embryo transition 1. The protein is ubiquitously expressed but enriched in brain tissue, particularly the cerebellum 2. KIAA0513 interacts with KIBRA, HAX-1, and INTS4, positioning it in signaling pathways regulating neuroplasticity, apoptosis, and cytoskeletal dynamics 2. In disease contexts, KIAA0513 shows diagnostic relevance: it serves as a hub gene in hypertension-related miRNA-mRNA networks 3 and is among eight feature genes associated with Alzheimer's disease progression through metabolic dysfunction 4. Additionally, KIAA0513 is a risk-associated gene in pancreatic carcinoma prognosis 5 and exhibits methylation-expression correlations in neuroblastoma 6. At the epigenetic level, KIAA0513 displays tissue- and isoform-specific monoallelic expression in bovine placentas, suggesting imprinting regulation 7. Notably, KIAA0513 expression is downregulated in subordinate primates, linking it to social status-dependent vascular dysfunction 8. These findings suggest KIAA0513 functions as a multifaceted molecular hub integrating developmental competence, neurological function, and disease pathogenesis.
