ADAM28 undergoes autocatalytic pro-domain removal: a glutamate-to-alanine mutation in the catalytic site abolishes pro-domain removal even though the mutant is transported to the cell surface normally, indicating maturation is at least partly autocatalytic. Mature ADAM28 is accessible to cell surface trypsinization in COS-7 cells, indicating it functions mainly on the cell surface. Processing occurs in a late Golgi compartment. |

ProADAM28s (65 kDa secreted isoform) is processed and activated by active MMP-7 (matrilysin-1), generating 42- and 40-kDa active forms lacking the propeptide. Active ADAM28s cleaves IGFBP-3 in both free form and in complex with IGF-I or IGF-II; cleavage is blocked by EDTA, 1,10-phenanthroline, KB-R7785, TIMP-3, and TIMP-4. |

ATRA stimulation induces ADAM28 expression in human chondrocytes (HCS-2/8 cells and primary chondrocytes). Transfection of ADAM28 or its soluble alternatively spliced form augments proteoglycan release from cartilage; a mutant lacking part of the disintegrin domain does not, indicating the disintegrin domain is required for localization/substrate recognition in cartilage degradation. |

ADAM28 knockdown in HUVECs increases VWF in supernatant and elevates integrin β3, p-TP53, and cleaved caspase-3 in co-cultured gastric cancer cells; these effects are reversed by VWF knockdown. |

EBV nuclear antigen EBNA3C represses the ADAM28-ADAMDEC1 locus through interaction with KDM2B (histone lysine demethylase), which removes the activating mark H3K4me3. Concurrently, EBNA3C recruits Polycomb proteins BMI1 and SUZ12 to deposit H3K27me3 at the locus. These are two distinct repressive mechanisms. |
