The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 43 kDa (predicted molecular weight: 54 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
功能Degrades amelogenin, the major protein component of the enamel matrix and two of the macromolecules characterizing the cartilage extracellular matrix: aggrecan and the cartilage oligomeric matrix protein (COMP). May play a central role in tooth enamel formation.
组织特异性Expressed specifically in the enamel organ.
疾病相关Defects in MMP20 are the cause of amelogenesis imperfecta hypomaturation type 2A2 (AI2A2) [MIM:612529]. AI2A2 is an autosomal recessive defect of enamel formation. The disorder involves both primary and secondary dentitions. The teeth have a shiny agar jelly appearance and the enamel is softer than normal. Brown pigment is present in middle layers of enamel.
序列相似性Belongs to the peptidase M10A family. Contains 4 hemopexin-like domains.
结构域The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.
翻译后修饰Autoactivates at least at the 107-Asn- -Tyr-108 site.
细胞定位Secreted > extracellular space > extracellular matrix.
