ADAM (A Disintegrin And Metalloproteinase)[1][2] is a family of peptidase proteins.[3] It is also known as the adamalysin family or MDC family(metalloproteinase-like, Disintegrin-like, cysteine rich). ADAMs are classified as sheddases because they cut off or shed extracellular portions of transmembrane proteins. For example, ADAM10 can cut off part of the HER2 receptor, activating it.[4] Therapeutic ADAM inhibitors can potentiate anti-cancer therapy.[citation needed]

It is categorized under EC 3.4.24.46.

Descriptions[edit]

ADAM Gene Description
ADAM2 ADAM2 is a subunit of an integral sperm membrane glycoprotein called fertilin, which plays an important role in sperm-egg interactions.[5]
ADAM7 ADAM7 is a transmembrane protein important for the maturation of sperm cells in mammals. ADAM7 is also denoted as: ADAM_7, ADAM-7, EAPI, GP-83, and GP83.[6]
ADAM8 The ADAM8 protein encoded by this gene may be involved in cell adhesion during neurodegeneration.

[7]

ADAM9 The ADAM9 protein encoded by this gene interacts with SH3 domain-containing proteins, binds mitotic arrest deficient 2 beta protein, and is also involved in TPA-induced ectodomain shedding of membrane-anchored heparin-binding EGF-like growth factor.[8]
ADAM10 ADAM10 (EC#: 3.4.24.81) is a sheddase, and has a broad specificity for peptide hydrolysis reactions. [9]
ADAM11 The ADAM11 gene represents a candidate tumor suppressor gene for human breast cancer based on its location within a minimal region of chromosome 17q21 previously defined by tumor deletion mapping.[10]
ADAM12 ADAM12, a metalloprotease that binds insulin growth factor binding protein-3 (IGFBP-3), appears to be an effective early Down syndrome marker.[11]
ADAM15 Through its disintegrin-like domain, this protein specifically interacts with the integrin beta chain, beta 3. It also interacts with Src family protein-tyrosine kinases in a phosphorylation-dependent manner, suggesting that this protein may function in cell-cell adhesion as well as in cellular signaling.[12]
ADAM17 ADAM17 is understood to be involved in the processing of tumor necrosis factor alpha (TNF-α) at the surface of the cell, and from within the intracellular membranes of the trans-Golgi network.

ADAM17 also has a role in the shedding of L-selectin, a cellular adhesion molecule.[13]

ADAM18 The protein encoded by this gene is a sperm surface protein.[14]
ADAM19 This member is a type I transmembrane protein and serves as a marker for dendritic cell differentiation. It has also been demonstrated to be an active metalloproteinase, which may be involved in normal physiological and pathological processes such as cells migration, cell adhesion, cell-cell and cell-matrix interactions, and signal transduction.[15]
ADAM22 This gene is highly expressed in the brain and may function as an integrin ligand in the brain.[16]
ADAM23 This gene is highly expressed in the brain and may function as an integrin ligand in the brain.[17]
ADAM28 The protein encoded by this gene is a lymphocyte-expressed ADAM protein.[18]
ADAM33 This protein is a type I transmembrane protein implicated in asthma and bronchial hyperresponsiveness.[19]
