ADAM19 (meltrin beta) participates in the proteolytic processing of membrane-anchored neuregulin-1 beta (NRG-beta1), with preference for beta-type NRGs over alpha-type; overexpression potentiates NRG-beta1 processing while protease-deficient mutants exert dominant negative effects; processing occurs intracellularly rather than at the cell surface. |

Recombinant soluble ADAM19 exhibits metalloprotease activity (autocatalytic tag removal, cleavage of myelin basic protein and insulin B chain), is inhibited by hydroxamic acid metalloprotease inhibitor BB94 but not by TIMPs 1-3, cleaves peptides corresponding to TNF-alpha, TRANCE, and KL-1 cleavage sites in vitro, and negatively regulates KL-1 shedding in cells rather than acting directly as its sheddase. |

ADAM19-mediated ectodomain shedding of NRG-beta1 occurs specifically in lipid rafts of neurons; the membrane-anchoring region of ADAM19 is required for its lipid raft localization, and NRG-beta1 shedding is not enhanced if ADAM19 cannot reach the lipid rafts. |

ADAM19 (meltrin beta) mediates ectodomain shedding of NRG-beta1 in the Golgi apparatus (not at the cell surface); subcellular fractionation showed soluble NRG-beta1 generated by ADAM19 is recovered in Golgi-enriched fractions, whereas TACE/ADAM17-cleaved NRG-beta1 is in lighter fractions; fluorescence correlation spectroscopy in living cells confirmed conversion of GFP-tagged NRG-beta1 from membrane-anchored to soluble form within the Golgi. |

Human ADAM19 autolytic processing within its cysteine-rich domain (at Glu586-Ser587) is regulated by disulfide bonds; DTT treatment and acidic pH (6.5) block autolytic processing, while pH 8.5 promotes it; specific cysteine residues (Cys605, Cys633, Cys639, Cys643) in the C-fragment are partially responsible for covalent association between N- and C-fragments; ADAM19 is activated by furin-mediated prodomain cleavage followed by intramolecular autolysis. |

ADAM19 is the protease responsible for cleaving the (pro)renin receptor ((P)RR) in the Golgi, generating an amino-terminal fragment (NTF-(P)RR) that is secreted into the extracellular space; transfected ADAM19 evokes (P)RR shedding and dominant-negative ADAM19 suppresses it; furin is not responsible for this cleavage; secreted NTF-(P)RR induces prorenin activity. |

In Xenopus, ADAM19 functions non-proteolytically in neural crest specification by physically interacting with its close paralog ADAM13 and inhibiting its proteasomal degradation, thereby sustaining Wnt signaling at the neural plate border; canonical Wnt signaling activity is severely downregulated upon ADAM19 knockdown, and ectopic expression of proteasome-resistant ADAM13 mutants rescues neural crest induction via Wnt signaling. |
