ADAMTS16 - ADAM metallopeptidase with thrombospondin type 1 motif 16 | Elisa - Clia - Antibody - Protein

Background

ADAMTS16 (ADAM metallopeptidase with thrombospondin type 1 motif 16) is a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) protein family. ADAMTS16 contains several characteristic domains of the ADAMTS family, including a signal peptide, a propeptide region, a metalloproteinase domain, a disintegrin-like domain, and multiple thrombospondin type 1 (TSP1) motifs. ADAMTS16 is expressed in various tissues during development and in adulthood. It is found in tissues such as the heart, lungs, kidneys, and skeletal tissues.It may play a role in processes such as chondrogenesis and osteogenesis where it regulates ECM composition and structure. ADAMTS16 expression levels have been found to be dysregulated in various cancers, including breast cancer, ovarian cancer, and prostate cancer. Its roles in ECM remodeling and tissue development suggest potential contributions to tumor progression, invasion, and metastasis. Dysregulation of ADAMTS16 activity has been associated with musculoskeletal disorders such as osteoarthritis and intervertebral disc degeneration. In these conditions, ADAMTS16 contributes to the degradation of ECM components within cartilage and intervertebral discs, leading to tissue degeneration and joint dysfunction.

Protein Structure

ADAMTS16 exhibits a multi-domain structure typical of the ADAMTS family:

• Signal Peptide: Directs the nascent protein to the secretory pathway.
• Propeptide Domain: Keeps the enzyme inactive until it is cleaved to activate the enzyme.
• Metalloprotease Domain: Contains the catalytic site with a zinc-binding motif essential for its proteolytic activity.
• Disintegrin-Like Domain: Facilitates interactions with integrins and other cell surface receptors.
• Thrombospondin Type 1 Repeats (TSP1): ADAMTS16 contains multiple TSP1 motifs involved in binding to ECM components and other proteins, aiding in cell adhesion and signaling.
• Cysteine-Rich Domain: Contributes to the enzyme's stability and interactions.
• Spacer Domain: Connects other domains and influences substrate specificity and binding.

Classification and Subtypes

ADAMTS16 is classified within the ADAMTS family, which includes various enzymes sharing similar structural domains. There are no specific subtypes of ADAMTS16, but it shares functional and structural characteristics with other members of the ADAMTS family.

Function and Biological Significance

ADAMTS16 is involved in several key biological processes:

1. Extracellular Matrix Remodeling: Cleaves components of the ECM, contributing to tissue remodeling and maintenance.
2. Development: Plays a role in the development of various tissues, including the reproductive system and the cardiovascular system.
3. Homeostasis: Involved in maintaining tissue homeostasis by regulating ECM turnover.
4. Reproductive Function: Research indicates a role in gonadal development and function.

Interactions

ADAMTS16 interacts with several proteins and cellular components:

1. Extracellular Matrix Proteins: Cleaves proteoglycans and other ECM components, participating in ECM turnover and remodeling.
2. Integrins: The disintegrin-like domain facilitates interactions with integrins, affecting cell adhesion, signaling, and migration.
3. Growth Factors and Cytokines: Modulates the activity of various growth factors and cytokines, influencing cellular behavior and tissue responses.
4. Thrombospondins: The TSP1 motifs mediate interactions with thrombospondins and other ECM proteins, playing a role in cell-matrix communication.

Clinical Significance

ADAMTS16 has significant clinical implications in various contexts:

1. Reproductive Health: Altered expression of ADAMTS16 is associated with reproductive issues, such as abnormalities in gonadal development and function.
2. Cardiovascular Diseases: Given its role in ECM remodeling, ADAMTS16 may be involved in cardiovascular diseases where ECM integrity and remodeling are critical.
3. Cancer: Dysregulation of ADAMTS16 expression has been linked to cancer, particularly in its role in the tumor microenvironment and metastasis.
4. Renal Diseases: There is evidence suggesting a role in kidney development and function, with implications for renal diseases.

Summary

ADAMTS16 is a vital enzyme in the ADAMTS family, contributing to ECM remodeling, tissue development, homeostasis, and reproductive function. Its multi-domain structure, including the metalloprotease and TSP1 domains, enables it to interact with various ECM components and cellular receptors.
